The ARA-1220 and ARA-1220-101 antennas are wide band, omni- directional, vehicular communications antennas. The ARA-1220 and ARA-1220-101 are designed for use in the most demanding and harsh tactical conditions. The lightweight, low-profile construction combined with a standard NATO 4-Bolt mounting pattern allows it to be easily integrated into military vehicles and most antenna mast systems.
The ARA-1220 has been tuned for performance between 1200 MHz and 2000 MHz but performs well up to 2500 MHz. The ARA-1220-101 version of this antenna includes a bandpass filter and low noise preamplifier built-in. DC power is applied and decoupled from the single RF connector at the base. The bandpass filter on the ARA-1220-101 reduces the band to operate between 941.5 MHz and 1126.5 MHz.
The maximum gain has been tuned for -10° to 10° in elevation with azimuthal variations ±1 dB. Broadband, low SWR ensures no effective radiated power reduction in mobile or vehicular platforms.
