[600MRG] Short Radial Observation - Updated

[D.J.J. Ring, Jr.]

Come on, Dave, you think that ISOTRON would work on 630m?

I always thought they were RF birdcages not like the G4ZU birdcage of 60
years ago which was like a SWISS QUAD and worked pretty well on 20m.

I am with you, loops are the best, even a poor loop beats a typical ham
vertical.

Now if you had two 300 foot towers with 300 heavy wire between them,  fed
midway with 300 feet of wire in a Marconi T arrangement with 360 one half
wave radials around the base, it would work better, but only the government
had that kind of money.

I'm with you on the loops.
