[TowerTalk] Comparing Hi-Z Receive Arrays and KB7GF Shared ApexLoop

[Dan Schaaf]

David, I know John W4NU. We both have the same HiZ system. I had to purchase 
the empty lot next to me to install mine whereas he had a deeper house lot 
and put his HiZ way back on his lot.

Yes, if you have a city lot only, then the loops are the only real 
alternative and the SAL may be the best solution.  To keep it simple, it 
could be made similar to my K9AY loop in that you have one solid vertical 
fiberglass support and two horizontal fiberglass rods all of which have the 
wires tie wrapped to the supports. Then put the whole assembly on a rotator 
and then you can zero in on the DX using the rotator.

That 80 X 80 foot requirement puts the HIz receiving array out of the reach
of many using small loops like the K9AY on city lots.

W4NU has something like the HIz which use uses on 160.  He had to clear out
a lot of land to use it.  As I recall about 1 acre.

I tried snakes and small loops but replaced them with a Shielded Link loop
described by AB0X in a 1989 CQ.  My shielded link was made from RG58 and
laid on my roof.  I did install a single K9AY loop with Gary's help in about
1994.  Broadside NE and SW and fed with RG8X to a P-408 Palomar Pre-amp at
the shack.  Beat the shielded loop om most DX and lasted until last year
when a tree branch brought most of it down.

WF4W told me he liked the Pixel Loop several years ago.  I understand he is
installing beverages now that he lives on a large property way outside of
Atlanta.
