872/872F-70-2TM

Frequency Range: 138-174/215-225 MHz

Gain: 5.0-5.5, 5.0/5.5dBd

The 872/872F-70-2TM antenna is a wide band dual band antenna designed for multicoupled systems. The antenna covers the 138-174 MHz and 215-225 MHz band, and offers a choice of radiation patterns that are determined by the dipole-to-mast spacing. This antenna is very rugged. It has an internal cabling; it is not field adjustable. The 872/872F-70-2TM antenna is well suited for use in severe environmental conditions. The antenna is offered in a ¼, ⅜ or ½ wave pattern spacing versions.
