Type 9-33-26 VHF/UHF Broadband Antenna | 30 MHz - 512 MHz

Product Description

The 9-33-26P3 VHF/UHF Broadband Antenna is designed to provide communications over the 30 MHz to 512 MHz frequency range for general purpose airborne applications. This VHF/UHF antenna is configured as a broadband fan monopole incorporating a frequency dependent matching network to ensure acceptable VSWR at lower frequencies, while preserving optimum gain at higher frequencies. A susceptance compensation network is included for gain enhancement at lower frequencies. The 9-33-26P3 is composed of a pressure molded composite radome housed within which houses the electrical assembly, and an aluminum alloy baseplate supports a single RF connector.
