Steve,

Is the Polyphaser strictly a shunt element (gas tube to groundf)? If so,
perhaps you 
can place it across the line with a "T" connector and still get protection.

HI all.  Have an application problem.  An Ameritron remote switch  passes 14 
vdc through coax for control circuit.  We are trying to find a coax line 
surge protector that is not a "DC blocked" type OR we also are looking for 
suggestions as to the best remote switch for 3 or 4 antennas, which would run 
on a separate control cable, not thru the coax .
  Any thoughts on either question is appreciated.  The PolyPHaser line, which 
we handle, will only pass DC on certain protectors at UHF, low power.  ALL 
the HF in line protectors are DC blocked which is inherent to these 
preferable, gaseous state, devices.   Thanks very much,  Steve,   K1PEK
