RF-3070-AT242
Soldier Worn
Active L1/L2 GPS
Antenna
The RF-3070-AT242 is a portable, active L1/L2 GPS
antenna with an integrated pendant coaxial cable and
magnetic mount. The 3-foot long RG-174 coaxial cable
terminates in a right angle SMB connector for direct
connection to the AN/PRC-117G(V)1(C) and RF-7800M-MP
Falcon III® manpack transceivers. The magnetic mount has
a retaining force of approximately 18 lbs.
This 2-inch square antenna incorporates band-pass filtering
that allows it to achieve greater than 40 dB of rejection at
± 50 MHz. It also incorporates a limiter that protects the
antenna from damage from electrostatic discharge and
co-located in-band interference. Furthermore, the GPS
antenna contains a 33 dB low noise amplifier (LNA) that
helps to both minimize the noise figure and optimize the
sensitivity of the antenna.
The size of the antenna is convenient for stowing in
either the soldier’s rucksack or any spare pocket
located within 3 feet of the radio connector. For
optimal satellite reception, the antenna should
remain upright with the magnets facing the
ground.
