Hello to All,
"The RF has to go somewhere" is the truest statement, I
have heard in a while. In the late 1980's I had a favorite Guard Rail at a
Motel in Atlanta. 75,40 and 20 meters were no problem. That's back when I
traveled for work. Four years or so ago, when Brenda/KK4CJG and I became a
Hot Item. I loaded my radio into the Aluminum Roof of her Brick Triplex. it
worked so well that I thought about just leaving things that way. Now we
run 134 foot Flat Top fed with 78 feet of 450 ohm window line. There is a
1:1 Current Balun just outside the window for the coax to exit. I keep the
Coax as short as possible between the Balun and the Ladder/Window Line. It
works really well. Yes, it has been plotted and I had a Smith Chart on the
antenna years ago. ON 15,20 and 10 meters there are some major lobes.
Someone with a fancy Computer program should post some info on this design
for me and others. I lost my documentation and have been too lazy to do
anything about it. Plus, I don't have the programs! it works from 80 - 6
Meters with the MFJ-989C Tuner and the antenna is at 30 feet high.
