I recall reading somewhere that Litz wire is only worthwhile up to something like 1200 kHz; if i don't have that figure quite right, i recall that the...
Small tv sets often come with a separate small loop for the high bands. I have one here which measures about 8 inches in diameter. I believe that FM...
There was a retired ham in Maryland that used to hand make an excellent tuned loop that he named the "Torus Tuner". He made 2 versions, one for MW and one for...

I tried tuning up for the first time on my Cu loop and was able to get swr to 1.0 but never at my frequency of interest. I tried changing the tuning cap range....
After being off the air for 10 years or so, I put up a big (about 500') loop antenna hung in the trees at our new place in the boonies of northern Minnesota....
I have a new copper pipe loop, 3' dia octagon with an air variable cap. I want to set the loop to resonance prior to installing the gamma match. What is the...
Hello, the Wise ones! I sent for ferrite rods from LY2KW in Lithuania and received 48 of 10mm x 200 mm (3/8" x 8") rods. My question is: how to best construct...
The brazing material I'm planning to use is 56% silver and 22% copper. That should make for a high conductivity attach between the copper vanes and spacers...
I've been researching some ways to join my copper cap together and come across silver brazing. From what I've read so far it seems that 56% Silver, Cd free...
I have for sale an MFJ 1786 Loop Antenna for sale. Asking $100 plus actual shipping charges. It was on a vacation house for several months and worked fine....
Hi, what is the "L" configuration? having a hard time imagining what it could be thanks, Grant KT6L [Non-text portions of this message have been removed]...
Hi, How do I know how many turns of wire do I need for my loop antenna? In case you need the dimensions it is going to be 11 11/16 inches wide and 13 3/4 Long....
When was that Heathkit Dipmeter sold? I am always interested in how long it took for the foam padding to turn to greasey tarry petroleum cheesecake. I scraped...
