[TenTec] OT: Openwire/Window Line and Bad Wx

[Stuart Rohre]

Actual parallel line experience:  One Field Day we arrived at our usual 
site to put up a 300 foot around horizontal loop.  We usually corner fed 
the Delta shaped loop at a corner with 450 ohm line we keep in Field Day 
stocks.  About 50 feet at most was our usual feed, but we had a big 
wooden spool of various parallel ladder line lengths 450 and 300 ohms.

There had been and continued to be off and on, huge rains.  We could not 
set up the tent on the ground that was flooded.  The closest paved area 
was over 200 feet away.  We tied off ladder line to trees and spliced 
more in with wire nuts, and even added in a stock of 300 ohm ladder 
line, until we reached the new location of the tent.  The Dentron Super 
Tuner as always with that loop; was hooked up with a 4:1 balun external 
to the Tuner.  Static discharge resistors of 150 k ohms went to a ground 
rod from each conductor right at the balun balanced side.

We found that the Tuner had no trouble matching the mixed up combination 
of differing impedance ladder lines, nor did we detect any signal losses 
compared to the usual shorter ladder line feed.
