This is a high performance 1:1 current-type balun with frequency range 0.5-60MHz and will handle up to 2kW power (PEP). Special ferrite toroids manage reactance and provide the very high inductance values necessary in a 1:1 balun.
It's Japanese construction and the broad frequency coverage will give excellent results in every application you are going to use it. It will help reduce unwanted radiation on the antenna feeder and can be also a help to minimise any local interference/TVI etc. Fitted with the popular SO-239 socket. This balun is well engineered and tested. It will not heat up under heavy-duty power, duty cycles, or stressing load conditions.
