Subject: Re: [TowerTalk] Vertical dipole other choices?
<I actually did the same scenario here. I have a full size 40M dipole at 115
feet and I fabbed a vertical full size dipole for 40M and hung it from the side
of the tower for comaprison. On DX the vertical won hands down on every sig.
On closer in, stateside <stuff stuff the horizontal dipole was the best. Not
suprising, the vertical dipole has a lower angle of radiation. I also checked
to be sure the tower wasn't interacting with the vertical dipole to be sure it
didn't screw up th pattern. I am very pleased with the <vertical dipole's
performance (for DX)

## What did you make the 40m full sized dipole from, wire..or tubing ?
How far is it spaced away from the tower ? How high is the dipole on the
tower ? Is the top of the aprx 66 ft dipole close to the top of the
tower ?
My guess is, the tower is acting like a reflector behind the 40m vert
dipole. IF that was the case, you would see some amount of FB in the
opposite direction..and some FS.
