The F-3980 is a wide band dual antenna with an 871F-70 on the base and a 792-70 on the top. The antenna offers for the 871F-70 a choice of radiation patterns that are determined by the dipole-to-mast spacing. The F-3980 has an internal cabling and is not field adjustable. The 871F-70 antenna is offered in a ¼, 3/8, or ½ wave pattern spacing versions. SPEC Sheet

F-3990 This VHF antenna is designed for applications that require peak performance in the 136-174 MHz while tolerating a VSWR around 2.0:1. This antenna has a loading coil between the radiating element and the base. This coil increases the electrical length and makes the antenna perform electrically as a 1/4 wave antenna, but shorter than a regular 1/4 wave antenna. Typical gain, when mounted on a ground plane, is comparable to a full 1/4 wave. Mounts on NMO. The upper element is made from a brass wound cable with a flexible shaft core, well sealed using rubber shrink material. This solution offers a high reliability and prevents breakage or brittleness. Other frequencies are available upon request. DOWNLOAD PDF

Our Control Station Combiners (CSC) is an ideal solution to reduce the number of antennas required on a communications site by maintaining a high radio-to-radio isolation at all times. It can significantly reduce tower clutter and loading, and simplify cabling installation at control center facilities. This product provides frequency-agile operation across a frequency range from 380 up to 512 MHz. This combiner has the possibilities to be connected to two antennas TX and RX. In case of only one antenna is used for TX and RX, an external duplexer is required. DOWNLOAD PDF
