VHF/GPS Antenna

The 21-50-110 is a combination, vertically polarized VHF communications and circularly polarized GPS antenna suitable for mounting on the upper surfaces of helicopters and sub sonic fixed wing aircraft.

Designed as a short, top loaded monopole for VHF communications and having a top mounted patch antenna for GPS, this antenna has separate decoupled feeds to allow for simultaneous operation of both systems.

Mechanical construction uses a glass reinforced thermoplastic shell with foamed-in-place internal elements. N-type (VHF) and TNC (GPS) connectors are fitted to the aluminum base plate which is DC grounded for p-static protection.
