The -915 RF Isolator is a 1:1 Current Balun, designed to be placed in line with any 50-Ohm coax. The RF Isolator is effective from 1.8 to 30 MHz. It was designed to improve the performance of all amateur stations, fixed or mobile. -915 will reduce or eliminate stray RF often found on coax. This stray RF can cause burns, TVI, interference and other problems with electronic equipment in ham-shacks and vehicles. Stray RF also results in a loss of radiated power from the antenna, which will lead to a great reduction in signal strength.
Use of the -915 will increase the efficiency of all amateur stations. Great when used in conjunction with a TVI filter too. SO-239 Input & output connectors.
