CB radio was the communication "thing" before message boards.
I had a set up with side-band as well as rotatable vertical/horizontal beam and a 360 degree ground plane antennas.
Man those were the fun days !
I am stuck with an Imax 2000 with the feedpoint at about 20 foot.
Basically, nearly the bare minimum.
My radio is tweaked to what is legal and for what it can do continuously as long as a fan is on it (lol).
(There is mass confusion over what is 'legal power'. If you read it correctly, the law says that your unmodulated signal is limited to 4 watts. (Technically, this is enough to talk around the world on 11m.)
That will be considerably higher when you speak into the mic. Many manufacturers misread this and actually limit the total output to only 4 watts.
My radio deadkeys at 4 watts, which is the legal maximum. When I speak into the mic, the radio puts out what it is capable of.)
I can talk 30+ miles locally on a good night, rather consistantly.
I can get to Kentucky, Tennessee, New York, and North Carolina with skip.
Once each to Florida and California.
I have built better, but to put something like that at an elevation where it would be noticibly better would be difficult, if not illegal (height lmitations).
I have built a vertical, center feed halfwave (18 foot long) that should have a takeoff angle of 0°, which would give it outstanding range.
The problem would be getting it the ~2 wavelengths into the air and suspending the feedline a certain distance out from it at a 90° angle. (The alternative is to run it through the inside of the lower element and then make the connection at the center, but this also poses some difficulties of its own.)
Anyhow, on the ground, that one gives me about 13 miles when I run an old 40 channel handheld to it.
That radio only deadkeys about 1½ watts, and swings to about 5 watts.
