Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation and Other Information	Basis of Presentation and Other Information The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with the instructions to Form 10-Q and Rule 10-01 of Regulation S-X for interim financial information. All normal recurring adjustments considered necessary for a fair presentation have been included. Certain disclosures normally included in annual consolidated financial statements prepared in accordance with accounting principles generally accepted in the United States (U.S. GAAP) have been omitted. These unaudited condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements and notes contained in our Annual Report on Form 10-K for the year ended December 31, 2020. The preparation of the unaudited interim consolidated financial statements requires management of the Company to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenues and expenses and the disclosure of contingencies at the date of the unaudited interim condensed consolidated financial statements. These estimates are inherently subject to judgment and actual results could differ. Adoption of New Accounting Principles There have been no material developments related to recently issued accounting standards, including the expected dates of adoption and estimated effects on the Company's unaudited condensed consolidated financial statements and note disclosures, from those disclosed in the Company's 2020 Annual Report on Form 10-K, that would be expected to impact the Company.

Discontinued Operations

Discontinued Operations and Disposal Groups [Abstract]
Discontinued Operations	Discontinued Operations On August 26, 2020, Sprint Corporation ("Sprint"), an indirect subsidiary of T-Mobile US, Inc., ("T-Mobile"), on behalf of and as the direct or indirect owner of Sprint PCS, delivered notice to the Company exercising its option to purchase the assets and operations of our Wireless operations for 90% of the “Entire Business Value” (as defined under our affiliate agreement and determined pursuant to the appraisal process set forth therein). Shortly thereafter, the Company committed to a plan to sell the discontinued Wireless operations. On July 1, 2021, pursuant to the previously announced Asset Purchase Agreement (the “Purchase Agreement”), dated May 28, 2021, between Shentel and T-Mobile, Shentel completed the sale to T-Mobile of its Wireless assets and operations for cash consideration of approximately $1.94 billion, inclusive of the approximately $60 million settlement of the waived management fees by Sprint, and net of certain transaction expenses (the “Transaction”). The assets and liabilities that transferred in the sale (the "disposal group") were presented as held for sale within our historical unaudited condensed consolidated balance sheets, and discontinued operations within our historical unaudited condensed consolidated statements of comprehensive income. The transaction was structured as an asset sale for income tax purposes. As a result, no current or deferred tax assets or liabilities were included within the disposal group. While our long-term debt did not transfer in the sale, its provisions required us to fully repay all of the debt concurrent with the consummation of the sale. Our debt was therefore presented outside of the disposal group as a current liability as of December 31, 2020. Our related interest rate swap liabilities were also presented outside of the disposal group as a current liability as of December 31, 2020, because management terminated them at consummation. Because repayment of the debt is contractually triggered by the sale, the related interest expense and debt extinguishment costs were presented within discontinued operations under the relevant authoritative guidance. The carrying amounts of the major classes of assets and liabilities, classified as held for sale in the consolidated balance sheets, were as follows: (in thousands) December 31, ASSETS Inventory $ 5,746 Prepaid expenses and other 47,003 Property, plant and equipment, net 299,647 Intangible assets, net 176,459 Goodwill 146,383 Operating lease right-of-use assets 421,586 Deferred charges and other assets 36,470 Current assets held for sale $ 1,133,294 LIABILITIES Current operating lease liabilities $ 409,887 Accrued liabilities and other 8,770 Asset retirement obligations 33,545 Current liabilities held for sale $ 452,202 Income from discontinued operations, net of tax in the consolidated statements of comprehensive income consist of the following: (in thousands) Three Months Ended Nine Months Ended Revenue: 2021 2020 2021 2020 Service revenue and other $ — $ 100,963 $ 201,076 $ 302,488 Equipment revenue — 9,862 12,253 32,222 Total revenue — 110,825 213,329 334,710 Operating expenses: Cost of services — 28,567 38,144 95,242 Cost of goods sold — 9,600 11,964 31,565 Selling, general and administrative — 7,696 17,514 25,931 Severance expense — — 465 — Depreciation and amortization — 15,077 — 62,804 Total operating expenses — 60,940 68,087 215,542 Operating income — 49,885 145,242 119,168 Other (expense) income: Debt extinguishment (11,032) — (11,032) — Interest expense and other, net (733) (4,508) (9,434) (15,477) Gain on sale of disposition of Wireless assets and operations 1,224,815 — 1,224,815 — Income before income taxes 1,213,050 45,377 1,349,591 103,691 Income tax expense 326,724 11,868 363,227 27,269 Income from discontinued operations, net of tax $ 886,326 $ 33,509 $ 986,364 $ 76,422 Consummation of the sale triggered the recognition of approximately $21 million of incremental selling costs during the three months ended September 30, 2021, for contingent deal advisory fees and severance expenses, which are netted against the gain on sale of disposition of Wireless assets and operations. Additionally, also triggered by the disposition event, we recognized an $11.0 million loss on debt extinguishment and incurred interest expense of approximately $2.6 million on the termination of our interest rate swaps.

Revenue from Contracts with Cus

Revenue from Contract with Customer [Abstract]
Revenue from Contracts with Customers	Revenue from Contracts with Customers Our Broadband segment provides broadband data, video and voice services to residential and commercial customers in portions of Virginia, West Virginia, Maryland, Pennsylvania and Kentucky, via fiber optic, hybrid fiber coaxial cable, and fixed wireless networks. The Broadband segment also provides voice and DSL telephone services to customers in Virginia’s Shenandoah County and portions of adjacent counties as a Rural Local Exchange Carrier (“RLEC”). These contracts are generally cancellable at the customer’s discretion without penalty at any time. We allocate the total transaction price in these transactions based upon the standalone selling price of each distinct good or service. We generally recognize these revenues over time as customers simultaneously receive and consume the benefits of the service, with the exception of equipment sales and home wiring, which are recognized as revenue at a point in time when control transfers and when installation is complete, respectively. Installation fees, charged upfront without transfer of commensurate goods or services to the customer, are allocated to services and are recognized ratably over the longer of the contract term or the period in which the unrecognized fee remains material to the contract, which we estimate to be about one year. Additionally, the Company incurs commission and installation costs related to in-house and third-party vendors which are capitalized and amortized over the expected weighted average customer life which is approximately six years. Our Broadband segment also provides Ethernet and Wavelength fiber optic services to commercial fiber customers under capacity agreements, and the related revenue is recognized over time. In some cases, non-refundable upfront fees are charged for connecting commercial fiber customers to our fiber network. Those amounts are recognized ratably over the longer of the contract term or the period in which the unrecognized fee remains material to the respective contract. A related contract liability of $3.8 million at September 30, 2021, is expected to be recognized into revenue at the rate of approximately $0.2 million per year. The Broadband segment also leases dedicated fiber optic strands to customers as part of “dark fiber” agreements, which are accounted for as leases under Accounting Standards Codification 842, Leases, ("ASC 842"). Our Tower segment leases space on owned cell towers to our Broadband segment, and to other wireless carriers. Revenue from these leases is accounted for under ASC 842. Refer to Note 14, Segment Reporting , for a summary of these revenue streams. Below is a summary of the Broadband segment's capitalized contract acquisition and fulfillment costs: Three Months Ended Nine Months Ended (in thousands) 2021 2020 2021 2020 Beginning Balance $ 15,290 $ 12,780 $ 14,669 $ 11,005 Contract payments 1,532 2,195 4,747 6,128 Contract amortization (724) (1,013) (3,318) (3,171) Ending Balance $ 16,098 $ 13,962 $ 16,098 $ 13,962

The Company holds the related investments in a rabbi trust as a source of funding for future payments under the plan. The SERP’s investments were designated as trading securities and will be liquidated and paid out to the participants upon retirement. The benefit obligation to participants is always equal to the value of the SERP assets under ASC 710, Compensation . Changes to the investments' fair value are presented in Other income (expense), while the reciprocal changes in the liability are presented in selling, general and administrative expense. At September 30, 2021, an additional $0.9 million of SERP investments were presented as prepaid expenses and other (current assets) as we intend to liquidate certain investments to pay the current portion of our SERP obligation. Cost Method Investments : Our investment in CoBank ACB’s Class A common stock represented substantially all of our cost method investments with a balance of $10.1 million and $9.8 million at September 30, 2021 and December 31, 2020, respectively. We recognized approximately $0.5 million and $1.0 million of patronage income in Other income (expense) during the three months ended September 30, 2021 and 2020, respectively, and approximately $1.5 million and $3.0 million during the nine months ended September 30, 2021 and 2020, respectively. Historically, approximately 75% of the patronage distributions were collected in cash and 25% in equity. Equity Method Investments: At September 30, 2021, the Company had a 20.0% ownership interest in Valley Network Partnership (“ValleyNet”). The Company and ValleyNet purchase capacity on one another’s fiber network. We recognized revenue of $0.2 million from providing service to ValleyNet during each of the three months ended September 30, 2021, and 2020, respectively, and $0.5 million and $0.7 million during the nine months ended September 30, 2021, and 2020, respectively. We recognized cost of service of $30 thousand and $0.7 million for the use of ValleyNet’s network during the three months ended September 30, 2021, and 2020, respectively, and $1.1 million and $2.2 million during the nine months ended September 30, 2021 and 2020, respectively.

The delay stems from a FCC review of the aggregate ownership of CBRS spectrum by certain shareholders of the Company. The Company is in the process of resolving this issue. The Company does not believe that it is probable or reasonably possible of a material loss.

Leases [Abstract]
Leases	Leases We lease various broadband network and telecommunications sites, fiber optic cable routes, warehouses, retail stores, and office facilities for use in our business. These agreements include fixed rental payments as well as variable rental payments, such as those based on relevant inflation indices. The accounting lease term includes optional renewal periods that we are reasonably certain to exercise based on our assessment of relevant contractual and economic factors. The related lease payments are discounted at lease commencement using the Company's incremental borrowing rate in order to measure the lease liability and right of use asset. The incremental borrowing rate is determined using a portfolio approach based on the rate of interest that the Company would have to pay to borrow an amount equal to the lease payments on a collateralized basis over a similar term. The Company uses the observable unsecured borrowing rate and risk-adjusts that rate to approximate a collateralized rate. At September 30, 2021, our operating leases had a weighted average remaining lease term of 20.2 years and a weighted average discount rate of 4.4%. Our finance leases had a weighted average remaining lease term of 13.5 years and a weighted average discount rate of 5.2%. During each of the three months ended September 30, 2021 and 2020, we recognized $2.3 million and $2.3 million of operating lease expense, respectively. We recognized $0.1 million and $0.1 million of interest and depreciation expense on finance leases during the three months ended September 30, 2021 and 2020, respectively. Operating lease expense is presented in cost of service or selling, general and administrative expense based on the use of the relevant facility. Variable lease payments and short-term lease expense were both immaterial. We remitted $1.4 million and $1.2 million of operating lease payments during the three months ended September 30, 2021 and 2020, respectively. We also obtained $2.2 million and $2.4 million of leased assets in exchange for new operating lease liabilities recognized during the three months ended September 30, 2021 and 2020, respectively.

Debt

Debt Disclosure [Abstract]
Debt	Debt Our cash payments for interest were $10.4 million and $14.5 million during the nine months ended September 30, 2021 and 2020, respectively. As discussed in Note 2, Discontinued Operations , upon consummation of the Transaction, the Company used approximately $681 million of the proceeds received from the sale to fully repay all outstanding principal amounts under, and terminate, the Credit Agreement existing as of June 30, 2021 ("Prior Credit Agreement"). On July 1, 2021, the Company entered into a Credit Agreement (the “Credit Agreement”) with various financial institutions thereto (the “Lenders”) and CoBank, ACB, as administrative agent for the Lenders (in such capacity, the “Administrative Agent”). The Credit Agreement provides for three credit facilities (collectively, the “Facilities”), in an aggregate amount equal to $400 million: (i) a $100 million five-year revolving credit facility (the “Revolver”), (ii) a $150 million five-year delay draw amortizing term loan (the “Term Loan A-1”) and (iii) a $150 million seven-year delay draw amortizing term loan (the “Term Loan A-2” and, together with the Term Loan A-1, the “Term Loans”). The Credit Agreement includes a provision under which the Company may request that additional term loans be made to it in an amount not to exceed the sum of (1) the greater of (a) $75 million and (b) 100% of Consolidated EBIDTA (as defined in the Credit Agreement), calculated on a pro forma basis in accordance with the Credit Agreement, plus (2) an additional unlimited amount subject to a maximum Total Net Leverage Ratio (as defined in the Credit Agreement) of 4.00:1.00, calculated on a pro forma basis in accordance with the Credit Agreement, subject to the receipt of commitments from one or more lenders for any such additional term loans and other customary conditions. The availability of the Facilities to the Company is subject to the satisfaction or waiver of certain customary conditions set forth in the Credit Agreement. The Company may use the proceeds from the Revolver and the Term Loans to finance capital expenditures, provide working capital, and for other general corporate purposes of the Company and its subsidiaries, including the payment of fees and expenses in connection with the foregoing. The Term Loans will be repaid in quarterly principal installments commencing on September 30, 2023, with the unpaid balance of the Term Loans due at maturity, as set forth in the Credit Agreement. Rates for borrowing under the Credit Agreement are based, at the Company’s election, upon whether the borrowing is a LIBOR loan or a base rate loan. LIBOR loans will bear interest at an adjusted LIBOR rate (which shall be no less than 0.00%) plus an applicable margin ranging from 1.50% to 2.75% for the Term Loan A-1 and the Revolver and from 1.50% to 3.00% for the Term Loan A-2, depending on the Company’s Total Net Leverage Ratio. Base rate loans will bear interest at a base rate plus an applicable margin ranging from 0.50% to 1.75% for the Term Loan A-1 and the Revolver and from 0.50% to 2.00% for the Term Loan A-2, depending on the Company’s Total Net Leverage Ratio. In addition, under the terms of the Credit Agreement, the Company agrees to pay the Lenders a fee on undrawn portions of the Term Loans and Revolver from time to time. This fee rate is dependent on the Company’s Total Net Leverage Ratio and ranges from a rate per annum equal to 0.200% to 0.375%. The Credit Agreement contains representations and warranties, and affirmative and negative financial covenants usual and customary for similar secured credit facilities, each of which are applicable to the Company and its subsidiaries, including covenants governing the ability of the Company and its subsidiaries, subject to negotiated exceptions, to incur additional indebtedness and additional liens on their assets, engage in mergers or acquisitions or dispose of assets, pay dividends or make other distributions, enter into transactions with affiliated persons, make investments or change the nature of the Company’s and its subsidiaries’ businesses. The Company is also subject to certain financial covenants to be measured on a trailing twelve month basis on the last day of each calendar quarter. These covenants include: • maintaining a Total Net Leverage Ratio (as defined in the Credit Agreement) not greater than 4.25 to 1.00 (subject to customary increased leverage periods following certain qualifying acquisitions); and • maintaining a Debt Service Coverage Ratio (as defined in the Credit Agreement) not less than 2.00 to 1.00. Indebtedness outstanding under any of the Facilities may be accelerated upon the occurrence of an Event of Default (as defined in the Credit Agreement). As of September 30, 2021, the Company had not drawn on the Term Loans or the Revolver and was in compliance with the financial covenants in its credit agreements. Rate quotations provided by a group of banks that sustain LIBOR will no longer be required after 2021. As a result, it is uncertain whether LIBOR will continue to be quoted after 2021. Our term loans and revolver identify LIBOR as a reference rate and mature after 2021. Alternative reference rates that replace LIBOR may not yield the same or similar economic results over the terms of the financial instruments. The transition from LIBOR could result in us paying higher or lower interest rates on our current LIBOR-indexed term loans. Our Credit Agreement includes provisions that provide for the identification of a LIBOR replacement rate. Due to the uncertainty regarding the transition from LIBOR-indexed financial instruments, including when it will happen, and the manner in which an alternative reference rate will apply, we cannot yet reasonably estimate the expected financial impact of the LIBOR transition.

The disposition of Wireless assets and operations triggered the recognition of an estimated current tax liability of $428 million scheduled to be paid during the remainder of 2021.

Investment	SERP Investments at Fair Value: The Supplemental Executive Retirement Plan (“SERP”) is a benefit plan that provides deferred compensation to certain employees. The Company holds the related investments in a rabbi trust as a source of funding for future payments under the plan.

The benefit obligation to participants is always equal to the value of the SERP assets under ASC 710, Compensation .
