Comant CI-273 UHF Antenna
Identical to CI-271 except its electrical performance is specified over the frequency range of 403 to 512 MHz in various band segments with VSWR limits shown. Stub antenna designed to withstand the harsh environments associated with the underside of an aircraft. Antenna radiator is mechanically captivated and is sealed against leakage. All exposed metal surfaces are nickel-plated for corrosion resistance and long service. The CI-273 mounts through single 0.600"" BNC connector is standard. Other connectors available. See P/N's to order a different connector.
