[TowerTalk] DC Pass Lightining Arrestors

[Clint Talmadge]

Gene et All,
I found these on PolyPhaser's site. The note says they are replaced by the GXZ series. That series has two models that cover HF  -- BUT -- they only come with TNC connectors. Those with N connectors which would be usable start at 400 MHz. 

Still no HF - DC Pass units that I can tell.

  Clint:

        Polyphaser's LNZ line of arrestors will pass DC.  They're advertised as intended for use with GPS systems that require DC for outdoor electronics.  You can read about them at http://www.polyphaser.com/productdata.aspx?class=lnz .

        I'm guessing you can order them through any Polyphaser distributor.  My choice is The RF Connection ( www.therfc.com .)

  I have done a search of the TT archives and found many references to PolyPhaser making a DC pass arrestor but have been unsuccessful in finding said item. I presently use the Alpha Delta Transitraps but would like to upgrade to either PolyPhaser or ICE. Both of these are DC blocked to the best of my knowledge.  Does PolyPhaser or ICE make a DC pass unit that I just overlooked or do I have to factor in the cost of a new antenna switch (presently using a RCS-4 with control voltage on the coax)? Or perhaps is there an alternative to the "Big Two"?

  On a side note I found a interesting web page on ICE's website that extols the virtues of ICE over PolyPhaser and it makes interesting reading. I understand they make a case for their own product but still interesting.
