[Lowfer] Loop antenna question

[Scott Tilley]

  Hi J.B.

I operate a number of full wave delta loops on most of the lower HF 
bands including 30m.  As far as I'm aware feeding like that would 
product vertical polarization.

What I find more important is the pattern of the loop.  I use a delta 
shape and feed the loop up 20% from the bottom corner to produce a near 
omni-directional pattern.  It works very well on 80-30m.  Don't have a 
tree tall enough to try it on 160m.
