Topband: inv. L

[Mike Furrey]

Hi Art,Yes, I have done that and am doing that. I use tall trees as supports and the 160 inverted L goes up one side of the tree then bent over horizontally to another tree over yonder. From the same feed point, the 80 meter section goes up the other side of the same tree and the top actually folds over an upper limb down to the tie point. I have had the antennas separate and had them from the same feed point as I do now and I have not seen much, if any difference in performance. With 600 watts output I have about 165 countries on 160 and about 220 on 80 from a small suburban lot in Houston. I just installed the same antenna in TN and it has worked quite well there. I feed it through a ferrite bead balun and I have one elevated (up about 20') per band.Hope this helps. 73, Mike WA5POK

 I was considering adding a second vertical element to my 160 inverted L.
This one would be roughly a quarter wave tall for use on 80.

I tried modelling in Eznec, but wasn't comfortable with the results. I may
have screwed it up.

Has anyone tried it for real? Is it a big compromise on either band? Would
a switch at the feedpoint have any benefit?

My inverted L has about 50 radials.
