Hi Gary. Greetings from the UK. Weather here raining so I have been playing around with my mag loop antenna. I like the Xmas light indicator and also the meter. So going to make one myself. Cheers from old George in the UK 🇬🇧 you may like my antenna. Made from car brake pipe. 😂

Make a kit and you could sell a ton of tne! Nice work!

My mla is fashioned from 1/2 inch Heliax. Currently set up with an old 3 gang varicap from an antique SW radio. Likewise I have one of those cheap Chinese SDR radios. Have made 4000 + QSOs with it in the last year. I can tune 20 and 30meters on the MLA, but the tuning is very sharp on 30. MLA antennas are interesting and mine receives very well, but the best sig report I have gotten was 349. It simply does not work well indoors which was why I built it to begin with as a means to get on the air from my bottom floor apartment. Perhaps I should build one of those caps and give it another shot.

Very clever! I'll try something like this for my magnetic loop antenna project.

Question? Can I do this with a roll of duct tape, a pair of channel locks, and a can of WD-40? Clint says, any man worth his salt, can fix anything with those three items! Seriously though, I thoroughly enjoyed your video and will be doing this little project ASAP! P.S. You probably just saved me a $1,000.00

Many thanks for your wonderful video. You have satisfied my curiosity as my little Sinclair Micromatic AM matchbox radio has a small postage stamp / compression tuning capacitor in it and I was wondering if one would work if up-scaled. Obviously it does! I made a magnetic loop antenna for CB radio and made a tuning capacitor from very thin aluminium sheet and fabricated vanes separated by nuts on long bolts. It works ok but your method is simpler and more robust and neater.

Gary, Wondered what the (insulating tape) thickness is and if you had tried different thicknesses or materials and what effect it had on capacitance and bandwidth tuning capability? How about the dimensions of the plates??? Thanks for giving me another project ! ...Rich N3JLR

The tape is .008 thick if the tape is too thick the lesser the compassionate son I went with 8,000 stick that way gives me a full range the capacitors should measure anywhere from 12 to 240 picofarads

Gary, this is a keeper, and I'm nominating you for the 'HAM Inventer Of The Year' award! I've always been interested in Transmitting Loops and built one many years ago with little success because I only had a small value cap with no gear reduction. I now know that I also had lots of RF feedback on my Coax each time I hit the key. I wasn't too smart back then. Oh well. Your cap design is an exorcize in simplicity and reliability, and I'll start building one in a few days after I replace the battery in my SUV. I will also build your Field Strength Meter as soon as I see your post on it. I thought you were going to use it to tune the loop, but you fooled me. Hi Hi.....
