[TowerTalk] 80 Meter Delta Loop

[kq2m at kq2m.com]

One antenna that does work well even over poor ground is a 4-square with 
elevated radials, preferably above .05 wavelength in height.  In my case 
I changed to a different design - instead of orienting the elements in a 
1/4 wavelength "box", I use custom designed 3/16 wavelength spacing to 
give a broader pattern which allows me to better hear/work ZS, Southern 
Africa and UA0 when pointed at Europe.
