FOR IMMEDIATE RELEASE:

          California Amplifier Reports FY 2005 First Quarter Results

            *  Q1 revenues up 140% from prior year to $45 million

            *  Q1 net income improves $2.4 million from prior year


Oxnard, Calif., July 13, 2004 - California Amplifier, Inc. (NASDAQ: CAMP)
today reported results for its first quarter ended May 31, 2004.

Revenue for the first quarter of fiscal 2005 was $45.0 million, compared
to $18.6 million for the first quarter of the prior year. The period over
period increase in revenue is due primarily to the improvement in the
satellite product sales which began late in the Company's fiscal 2004
second quarter.  Net income for the first quarter was $1.3 million, or
$0.07 per diluted share, compared to a net loss of $1.1 million, or $0.07
per diluted share for the first quarter of fiscal year 2004.

Fred Sturm, President and Chief Executive Officer, commented, "CalAmp is
in the early stages of re-defining the Company beyond its historical set
of customers and markets.  Integration of the Vytek business is well
underway and we are actively pursuing opportunities which will capitalize
on our combined strengths in RF and embedded software design, development
and manufacturing to provide a complete content delivery or communication
solution. The newly formed Solutions Division had revenues of $4.5 million
for the seven week period included in this quarter. The Solutions Division
experienced a loss of approximately $1.5 million during this period
including pre-tax charges arising from the acquisition for writing off in-
process research and development of $471,000 and an intangible asset
amortization expense of $234,000. We anticipate that with the major
elements of the integration effort being concluded during the second
quarter we will begin to see improving operational contribution from this
segment of our business during the second half of our fiscal year.  I am
also pleased to report that the consolidation of Vytek's product
manufacturing operation into CalAmp's Ventura County facility is
substantially ahead of plan and expected to be completed in July which
should further help to reduce costs going forward."

Mr. Sturm added, "During the quarter we continued to make progress in two
key product developments.  Beta testing of our "Directed AP" product for
the enterprise WiFi Access Point market is expected to begin during August.
Also, customer testing is underway of our satellite product targeted to
support improved Digital Video Recorder market penetration by one of our
major customers.  This product, which substantially reduces the cost and
complexity of installation of Digital Video Recorders, is undergoing set
top box compatibility and stress testing.  These tests are expected to be
complete in August, with production starting in our fiscal third quarter."

Mr. Sturm also noted, "Based on our current visibility, we estimate fiscal
2005 second quarter revenues in the range of $48 to $55 million and
earnings in the range of $0.05 to $0.09 cents per diluted share.  Included
in these estimates are charges of $434,000 for amortization of intangible
assets."
