 ```Hello, Since the question is back and actual. Never saw somewhere a particular cases as: - unequal distribution of radians. - my tower is a triangular selfsupported one. -My lot has a triangular shape. I can not reach all azimuths since the tower is only 20' away of the house which is about thirty width . Since I can't reach the grass directly from the base of the tower. What will happen if the distribution of the radials will start 6 or 7 foot from the tower, connected to a single wire. Not in all azimuth can be reached and more then half of the number will be shorter then a Lambda/4 ? More , is it allowed to change a radial from direction on its run. As one can see, this a very irregular shape.... After this question an other will follow about general behaviour of loaded Tower, and loading technicalities. Thanks for reading me.

Elevated radials are overrated. Unless you can get them up 1/4 wl or more in the air, you will still contend with ground losses when you only use a few radials. Also the system is NOT fully unbalanced when you use a small counterpoise. It is in the murkey land of not being balanced and not being totally unbalanced. > I am designing a 4-square for 80m.

When I tested systems at a few locations, I found I needed about 15-20 elevated radials (up about 6 ft) to equal 60 on the ground. You will still need a choke or current balun to cool off the feedlines in some cases even with 15 radials. _______________________________________________ See: http://www.mscomputer.com for "Self Supporting Towers", "Wireless Weather Stations", and lot's more.
