TxRx, Combilent

TX RX Systems, Inc. was founded in 1976 and is located in Angola, NY, a suburb of Buffalo. The company quickly became the industry leader in providing RF Conditioning products in the Land Mobile Radio market, aided by breakthrough inventions in T-Pass® Transmit Combiner, Auto-Backup® Tower Top Amplifier, base station antennas,  etc.  Over the years, TX RX’s RF Infrastructure Products have played a critical part in improving and optimizing numerous mission critical radio networks for both Public Safety and general two-way radio users. TX RX Systems was acquired by Bird Technologies Group in 1995 and became the “go-to supplier” for LMR applications in VHF, UHF, and 700/800 MHz frequency bands. In 2018, Indutrade, a European conglomerate based in Sweden, acquired TX RX from Bird.  TX RX joined Combilent, a Denmark company also owned by Indutrade, to form the Combilent Group.    The new TX RX will continue the tradition of offering best-in-class solutions for our customers, while leveraging the combined strength and resources of both companies in R&D, operations, and sales support.
