The BTY Series of professional quality antennas include single channel and broadband models designed for a variety of UHF and VHF applications. The BTY Series features high gain, narrow beamwidth, and low side lobes. All models can 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. On VHF models, the heavy duty mounting bracket is positioned at the antenna's center of gravity for balanced mounting to the mast. An optional cantilever mounting bracket (Stock No. 5760) is required for VHF antenna end mount installations. This optional mount permits attaching the VHF antenna to either a horizontal or vertical tower member. All UHF models are designed for end mounting due to their smaller physical size. The BTY Series Antennas can accommodate a maximum mast size of 2.5" O.D.(outside diameter). All models are 75 O impedance with an "F" connector.
