[Lowfer] MP Loop antenna reconfigured

[Mitch Powell]

Hi Andy:
I thought the picture would help....thanks for the comment.
Only 6-8 feet above ground.
No radials for the loop of course - they really are not required.... it's the 
reason that I have not installed a vertical system - but now that I have the
vertical pieces up - I might re-consider.
As you can guess - the vertical pieces go up over trees...so I am
surrounded ( within 50 feet in all directions )  by trees - which I
know will appear as RF sponges - particularly in the Spring-Summer
time.
Then I  really would require the radials.

by the way - thanks for all the captures. They certainly help in knowing that all
is well and no significant changes have occurred. A great service for all.

73 and a very happy and merry Christmas to you as well.
Mitch
