UHF Control Station Combiner – UHF CSC

Frequency Range: 380-512 MHz

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

F-3990 VHF Peak Performance Antenna

Frequency Range: Available for 136-174 MHz

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
