Model A8020
800 MHz Low Noise Pre-Amplifier
| The model A8020 is a
commercial/government grade low noise
receive pre-amplifier for use in the 800 MHz service band. It is designed to improve weak
signal reception on scanners or other wideband radio receivers,
including spectrum analyzers and related equipments used in signal
intercept platforms, trunk tracking
applications or for general monitoring in this band. The A8020 is
part of a system of components for the 800 MHz service band and may be
used in conjunction with our receiver multicouplers models MCA208M,
MCA204M and MCA804B.
This pre-amplifier features internal RF
relays for by-pass switching and can be left inline when not needed. It
may be mounted remotely in an equipment cabinet, or near the antenna,
and DC powered via the coax using an optional "Bias Tee". It is designed
to drive long runs of coaxial cable to overcome feed line losses, or,
may be used in any configuration when weak signals needs to be received. The
A8020 is housed in a cast
aluminum enclosure for ruggedness, high reliability and mechanical
stability required in many demanding commercial and government
installations. Black powder coating and a Lexan overlay
panel will stand up for many years of service.

Model A7020
700 MHz Low Noise Pre-Amplifier
|
The model A7020 is a commercial/government grade low
noise receive pre-amplifier for use in the 700 MHz service band. It is
designed to improve weak signal reception on scanners or other wideband

components for the 700 MHz service band and may be used in conjunction
with our receiver multicouplers models MCA208M, MCA204M.
Mechanical and electrical specifications are
similar to the A8020 and features internal
RF relays for by-pass switching and can be left inline when not needed.
It may be mounted remotely in an equipment cabinet, or near the antenna,
and DC powered via the coax using an optional "Bias Tee". It is designed
to drive long runs of coaxial cable to overcome feed line losses, or,
may be used in any configuration when weak signals needs to be received.
