Hybrid Combiner

Hybrid combiner is also a kind of antenna and feeder system equipment widely used in radio communication relay station. It can combine the transmission signals of multiple relay stations into one output port, and then transmit the signals through one antenna feed. This can not only reduce the number of antennas and feeders, but also save the engineering cost of tower erection.

Product Description

Overview:

Product Features:

This combiner uses the 3dB bridge broadband combiner, which is not limited by the channel spacing. It can be widely used for combining in systems with relatively close channel spacing, and solves the problem of sharing antennas for combining near channel spacing.
Small size, natural heat dissipation with radiator, high reliability.
Each output port is equipped with an independent isolator to ensure the standing wave characteristics of each port, so that the isolation of each port is high and mutual interference is small.
The single-section or double-section isolator can be used. The single-section insertion loss is small, the isolation degree is low; the double-section isolation degree is good, and the insertion loss is relatively larger.
The equipment body is made of aluminum alloy materials, with solid structure and light weight. It can be installed on a series of 19-inch standard frame, which is beautiful and atmospheric.
