A pair of government surplus Polyphase IS-50 protectors came my way recently and I'd like to use them on my 160M verticals to replace what I currently use. They are exactly alike in appearance to the IS-B50LU and similar, but a test reveals they have DC continuity. I can find nothing in Polyphaser's web page about a non-DC blocked device for a transmit antenna and carrying this part number.
Has anyone ever run across units like this, or are these in fact faulty? Bill VE3CSK _______________________________________________ UR RST IS ... ... ..9 QSB QSB - hw? BK
