N6BT’s ring is pretty flexible in its dimensions. It can be 3 or 4 sides (or 
anywhere in between) and can handle some variation in symmetry. 

I’ve been having issues finding a solution to the high tree attenuation on my 
property and I had an inverted L with the ring and another inverted L 340’ away 
with 60 x 100’ radials.  The model showed there was some interaction between 
the 2 antennas so exact difference was not known. But basically the ring was 
very close to the 60 radial version.   

One of the key issues is making sure the inverted L section is close to 
resonance. If it’s short, more current is moved into the ring which is not 
desirable.
