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?

A 20-meter "random wire" I experimented with over the weekend might
work in your setup. It's an end-fed wire -- the Arrl antenna book
recommends an odd number of quarter waves -- I chose three, making the
wire about 49 feet long, attached directly to an "L" antenna tuner in
the shack. I also attached a single elevated quarter wave radial to
the tuner chassis; just ran it out the window and along the house, and
that tamed whatever in-shack rf I had. Got an easy 1:1 match.

If your shack is on the ground floor, such a wire could go straight
up, and then across your roof. Use tiny wire; plastic button
insulators, zig-zag it, etc...
