If you had a situation where your space is limited adn a
vertical seems to be the last option, do you have any other way you would
go?
I do have limited space. I use an attic antenna consisting of 100' zig-zag
doublet fed with 450 ohm ladder line and a homebrew tuner. I have ran 1200
watts pep on 80m and 40m with this antenna. Of course no one can watch TV or
talk on the phone, or do anything else that involves electronics in the house
while I am on the air.
I have a small 20' X 56' back yard. I have used a zig-zag doublet inverted
vee style with apex at 40' and had pretty good results on 80m-10m.
