Thought some here, in between political rants, might like to see some
pix of my 7' shielded loop. This has replaced the 3' version- a picture
of which is included.
Although the summer QRN is high, the new loop is proving itself with
NDB's that I have never copied before. The Burhans amp was modified to
allow reception up through 17 MHz. Local power line noise, TV switches
etc are gone.

Main loop is from 5/8" CATV hardline and CATV connectors. The vertical
support mast is thin wall fiberglass with aluminum inserts at each end
to allow clamping- the entire support weights less than 1 pound. Now, to
get it on the rotator/tower.

Impressive Dale, very impressive. I was considering a 4-foot loop to replace
my 3-foot (also hunting for NDBs) but I backed off because I thought it was
too much of a challenge. Now after seeing your 7-foot loop, I'm getting my
courage back to try again. Nice job.

Looks great Dale.... BUT Nortons says you have a 'Malicious Script' embedded
in '10024'.

Hi Al,
I would try the 4' loop. My 1 meter loop was very impressive- I have never heard
MW as well- and as quiet. All the local power line noise, TV switching supply
garbage etc disappeared. I did direct comparisons with my active whip- the loop
won 100% of the time. The only reason I grew it was for the 136 and 185 KHz
experimental beacons.
I have a nice machine shop and great junk box- but total cost was only a couple
of bucks for the oddball toroids I did not have in stock.

Classy looking loop!
