The F-33031-D is a Wide Band Heavy Duty Omnidirectional Antenna specifically designed for trunked multicoupled and X-pass systems applications. This antenna is extremely rugged and is well suited for use in severe environmental conditions. This antenna is a Low Intermod design that incorporates a minimum of moveable joints in its construction and replaces standard castings with heavy duty welded joints. -
The F-3647 is a wideband dual antenna with an 871F-70 on the base and a 771-70 on the top. The antenna offers for the 871F-70 & 771-70 a choice of radiation patterns that are determined by the dipole-to-mast spacing. The F-3647 has an internal cabling and is not field adjustable. The 871F-70 & 771-70 antenna is offered in a ¼, 3/8, or ½ wave pattern spacing versions. The antenna can be black anodized. Heavy Duty version of the antenna is also available.
