BROADBAND VHF ANTENNAS

The BTYBroadband Antenna Series includes professional quality, broadband antennas designed for a variety of VHF applications. The BTY-LP-LB covers low band VHF channels 2-6 using 8 antenna elements, while the B T Y-LP-HB covers high band VHF channels 7-13 using 10 antenna elements. The BTY Broadband Antennas feature high gain, narrow beamwidth, and low side lobes. These antennas are designed with a two piece boom (assembled into one piece) allowing the antennas to be shipped via UPS to reduce freight and handling costs. Square boom construction and end-sealed aluminum elements provide added strength, excellent wind resistance and exceptional weathering properties. The heavy duty mounting bracket is positioned at the antenna's center of gravity for balanced mounting to the mast. These antennas can be rear mounted using a BTY-C-MOUNT Cantilever Antenna Mount. This style mount permits attaching the antenna to either the horizontal or vertical tower members. The BTY Series Antennas can accommodate a maximum mast size of 2.5" O.D. (outside diameter). These antennas feature a 75 W type "F" connector to provide feed on coaxial cable down leads.
