*Helped my friend.... Dale/KA4ZDR with mine. He does quite well with the
Multiband Dipole and the Ugly Balun. I Need to build another one. They work
GREAT. I was just concerned with the Loss of the Coax in my Windows/Ladder
Line to Coax Transformation. Total length of Coax out the window is 10 feet
to the Ladder Line. I know that there is loss there due to SWR but, You
have to do what you can with these Triple insulated and All Aluminum
windows. I never thought to ask the Engineers in our group, which set-up
would have less loss?*
