Folks,

*Continuation of Previous Thread: UHF Repeater Antenna Discussion*

We climbed the tower on Sunday and checked things with the wattmeter  
between the Feedline and the antenna.

At the bottom, we were making 75 Watts at the duplexer output. At the  
top, after going through 105' of LDF4.5-50A (just over 1dB of loss), a  
PolyPhaser, and a 6' jumper of RG400 (from the duplexer to the  
PolyPhaser) we were seeing 57 Watts. I show that as about 1.2 dB of  
loss, which seems quite reasonable. The F10, at the top, showed me  
about 1.5W reflected... or 1.34:1 VSWR.

The antenna is a DC grounded colinear, and we showed no measurable  
(with my DMM) resistance between the center pin and outer conductor of  
the Hardline/Antenna combination.

Right now, we're of the mind that the feedline is good.
