[TowerTalk] 160 Meter Antenna on a City Lot

[Alan Beagley]

What about a (folded) unipole with an ATU? See pp. 7-47f. of the ARRL's 
_Hints and Kinks_ (15th. ed.). That's what I'm planning to try when I 
get my tower up.

I have a 60 foot tower with a TH6DXX on the top, but my track record of shunt feeding the tower is not all that great.  Yes, I have a pretty good ground under it...not great...but OK.  I've used a lot of different variable caps on the shunt but tuning it has been 2:1 at best.

> How about a trapped dipole?  I can get a 80 meter inverted-vee on the lot.  So, I was wondering if a trapped system would work and how well?  I would think that the band width of such a device would be small, but so it s a shunt fed tower. as well as the Inverted-L.
