[TenTec] 80 meter loops

[Ron Feutz]

TT'ers,

My own experience is with a single vertical 40 M loop fed 1/4 wave down 
from the apex and built over the radial field of my 160M 4-square which was 
built on a swamp.  Pretty near ideal conditions for a vertical radiator. 
The bottom wire of the loop was just high enough so the deer could walk 
under.  The first contact was an Asiatic Russian who gave me a 20 over 
report - I was running 100 watts. I very seldom had to call any  EU, or 
VK/ZL more than once.  I'm at a new QTH now and would like to put up some 
more vertical loops, probably a couple of them in 2 element, switchable 
form.  I won't have the radial field or the swamp to enhance things, 
although I believe my ground is above average.

Has anyone here ever compared a 2 element parasitic vertical loop array, 
apex at 40-45',  to a shorty-forty at "usual" heights, say 60-70', or 
higher, say 110'?

73,
