Product Description
Overview:
The Multicoupler , also known as the receiving antenna sharing device, is a device that uses a pair of antennas to receive multiple channel signals at the same time and distributes the received signals equally to each receiver. It mainly includes: pre-filter, signal compensation low noise amplifier and multiplexer. The pre-filter is used to filter out unwanted signals outside the band, and the low-noise amplifier is used to compensate for the signal loss generated by the feeder and the signal distributor, so that the receiver's reception sensitivity is not affected by the loss of the antenna feed product. It effectively solves the problem of multiple sets of antenna feeds in multi-channel systems, thus reducing the system cost and improving the communication performance of the system.
Product Features:
- With cavity filter and filtering characteristics, it can effectively filter out unwanted signals in the air and reduce the interference of air clutter on reception.
- The signal compensation adopts the amplifier with excellent performance, low noise coefficient, good amplification effect, can effectively improves the influence of antenna feed on receiver sensitivity
- The equipment gain can be adjusted according to the project site, and the dial adjustment is accurate and convenient.
- 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.
