Topband: Recent Article on a 160M Vertical Delta Loop?

[Gary Smith]

I did not see the article but I had just 
that in the 90's. I had moved from a condo 
where I explored copper pipe and shortened 
octagon loops. Remembering my 
experimenting when the now Ex & I moved to 
a house and I had a tower, I experimented 
with loops again & this time delta wire on 
160.

I had a 110' fold over Heights tower and 
had a short delta for 160 attached with 
the apex at the top, held off about 15" 
from the tower. The corners were attached 
with ceramic egg insulators, It was center 
fed at the base which was about 20' high. 
I had a vacuum variable attached at the 
feed point and a length of around 10' of 
wire parallel to the tower, running 
upwards about 5" from the tower and held 
in place with ceramic stand-offs.

I controlled the vac variable via synchros 
and with it I could run the entire 160M at 
1.1 I'd love to have it again but I'd need 
a tall tower to make it effective. I 
didn't get the chance to make a matching 
short delta, one 90 degrees offset to see 
if I could switch between them and find a 
gain benefit in a given direction.

However, I did well with it for the few 
months I had it up, the next year I had to 
relocate and never had another tower 
since.

73,
