Raised verticals require tuned radials or a grid type ground ie a metal
roof or a screen with sufficient surface area to radiate a image of the
vertical element.
The power lines in the ally sounded like my installation I get a lot of
power line noise from them. (good luck)
I'm personally looking forward to getting my tower up and trying a
inverted "V" the ant. I have now is a Butternut HF6Vx.
I have a Timewave ANC-4 to help with the noise and it dose work but I'm
going to try the outside Ant. For it, I hope it will be more effective.

Subject: [TowerTalk] 80 meter vertical suggestion
Ok Antennanites.
Limited space.
My best chance is putting a vertical on my non attached garage roof.
That would make the base about 18 feet off the ground.
I could mount it directly to the roof a the center, have some rope guys
and
lay some unfortunately short radials on the garage roof.
I have the ON4UN book. What would be the best configuration for DX and
contesting. I'm mostly a cw type.
I'd like it to be a short as possible as the com ed power lines run
through
the alley and would be awfully close.
I could put it on the house roof which would be a higher ridgeline but
that
would put it right close to my tower/yagi.
