Thread: Balun in metal box

  1. #1

    Default Balun in metal box

    A metal box verses a plastic box. Does the balun care? If metal, any concern if the balun and/or wire is mounted solid against a metal wall? If so, amount of spacing?

    As baluns are wound on a core, any nearby metal object will have an effect; exactly to what extent I can’t say.

    All the baluns I have wound are in plastic outdoor electrical enclosures. All the commercial ones ai have seen are also in plastic enclosures.

    Kind regards,
