9-33-26 V/UHF Broadband Antenna The 9-33-26 is a combined VHF/UHF broadband antenna designed to provide communications over the frequency range 30 MHz to 512 MHz, and intended for use in general airborne applications. The 9-33-26 is configured as a broadband fan monopole incorporating a frequency dependent matching network to ensure acceptable VSWR at lower frequencies, while preserving optimum gain performance at higher frequencies. A susceptance compensation network is included for gain enhancement at lower frequencies. The 9-33-26 comprises a pressure moulded composite radome within which is housed the electrical assembly. This is enclosed at the base by an aluminium alloy baseplate which supports the single RF connector. 17 mm MAX 22.225 mm 173.5 mm MAX 17 mm MAX 22.225 mm Chelton Limited has a policy of continuous development and stress that the information provided is a guide only and does not constitute an offer or contract or part thereof.
