I am also on a small lot in a city with a 1 wavelength 80 m. horizontal loop. Actually mine is 1 w/l at around 4 mhz so where I operate it's really more like .8 or .9 w/l. my lot is 50 x 100 feet. I

If you have a support for the loop that is 560 feet tall then you don't need an inverted L; you can at the least put up a 1/4 w. vertical with no horizontal part at all. I am not sure what is limitin

It's an array of horizontal cage dipoles fed in phase by parallel wire feedline. The dipoles are out in front of a reflector screen. I don't know how many there are but the size of the entire steel s

Which brings up an important point. To some extent there's no one best way. What works for you depends on your environment. Tall trees out in the sticks with none nearby and plenty of unpopulated ro

Frank W3LPL is correct. Your problem isn't your antenna, it is what you describe as a PITA tuner! I use a low loop and ladder line (_ladder line_ not window line) for ragchewing all the time. Sure I

I'd never try 66' (20 m) of tubing each section 6' (1.8 m) long held only with hose clamps. That bottom clamp will be holding too much weight. Short and sweet: if you want that height and you want to

The dipole, at 300 ft. on 160 doesn't beat the 1/4 w. vertical because even 300 feet on 160 isn't high enough. That's like around 35 feet high for a dipole on 20 meters. High enough to make plenty of
