I am installing new coax from the tower to the shack and have inserted a 
polyphaser IS-50NX-CO,  N-style connector and wanted to check everything 
out from the shack to the tower before I connect it to the beam.  The 
polyphaser is located at an entrance panel some 30' from the shack.

The unit is not new but did come in the original box with all hardware 
and instructions, however, how do I check out the unit to know if its 
still good?

This is a DC blocking style so there's no connection between center 
pins, I have a MFJ antenna analyzer but I don't think it sees past the 
polyphaser fro the shack end.

How does one know if the unit is OK or not?  There is a varied opinion 
as to there worth and maybe I should select a different product.  I 
always disconnect the antennas in the shack but wanted to add some 
protection at the building entrance plus I can also disconnect the coax 
and also the rotor cables there.
