*Bob,*
* Hello and Thanks for the help. I am dumping the output from the Balun
or Ugly Balun ( depends on which is used ) into 450 ohm Window/Ladder Line
and a Dipole which is 126 feet long at about 35 feet high. The reason I use
the Window/Ladder line is because One Antenna has to do it ALL at the
present QTH. ( Multiband ) Does the 0.3 db loss still hold true? It is much
harder to hurt the RG-213. I sometimes get a Wild Hair and do almost Legal
Limit. Although the SB-220 really won't quite get there but, is a really
easy Kilowatt. I don't push anything to the limit. Don't know why I even
worry, the SB-220 has been cold for over 8 months. Guess I need to at least
fire it up in standby mode for a few hours this week! Maybe heat my Dummy
Load with about 150 watts of AM for a minute or two. If the 0.3 db figure
holds true, I will be at the Hardware Store for my PVC pipe in the morning!*
* Thanks from Wade/KJ4WS*
