Greg:

If cramped for space with a vertical, you could always use a short whip at
the top and helically wind the rest of the antenna to be one-half wave
electrical length and one-quarter physical length, and using a L-match to
feed it with coax. This would allow you to get by with no groundplane, if
you desired, you could feed it against a small counterpoise...

Warmest regards,
John

Hello to all,

I have searched but nothing fits the bill for what I want to do.
Anyways, right now I have a 20m homebrew dipole in my attic at about
20ft. I want to get a 20m wire antenna outside but I live in a condo.
I have, as I see it, two options-

1. Put a vertical dipole from my chimney (35ft) to the ground. I have
a very small patio area so the angle of the wire will be about 70-80
degrees.

2. There is about 100 ft between two unit chimneys. As no antennas
are allowed, however there is a satellite dish at every turn, I would
need to be super stealth and get permission from the neighbors that own
the other chimney (good luck on that), but I could put a dipole between
the two chimneys.

I have looked into a vertical, but I have no room for radials. My
patio is 6 ft deep and maybe 10 ft long.

Any suggestions?
