Are the two capacitors in series (both fixed legs of the trombone connected each to one end on the big loop)?

So Xmas ?

GREAT FOR 10 SECONDS THEN HE BECAME SO SO SO SO BORING!!

The sound could be better.... From one professional to another....

very nice! and well explained

I just looked for a part 2. I'm quite curious as to how your Loop turned out. I can just kick myself because I had a Vacuum Variable Capacitor years ago and gave it away. I want to build a Loop someday so I've been watching for Capacitor ideas.

Brillant idea and well constructed.

No measurements?!

👍

I find it fairly fortunate that that conduit fit so nicely inside your outer trombone tubes. Have you published the specification for that tubing and conduit? This is definitely something I'm probably going to want to give a go.

Thats amazing difference. I've always been put off by these antennas due to the high voltage on the capacity. Anything over 9v and i get nervous! (ie anything that will make my touch tingle). I'm plagued by broadband noise in my area, and i think I'm going to dust off an old mag-loop project and give it a try. YT is a real powerful medium for sharing of these ideas. Very inspirational. Thanks for taking the time to share.

Very tidy. I've been doing something similar with copper pipe, but doubled up on the trombone idea to increase capacitance. Not tried it yet, its been one of the projects sitting in the shed for a while - you have inspired me to go dig it out and finish it off! Thanks for sharing.

Did you find you were able to null-out any noise by turning the loop. Likewise, peak the signal from that barely-audible station by rotating the loop?

very nice de VU3FTP

question.... what amount of transmit bandwidth does it have??

have you measured the capacitance of the cap?

send me a project please

Two sets of this in parallel, may tune 80 meters

How power do think the capacitor can handle?

what bands will it tune with that capacitor?

Charles, after a month, you certainly deserve more views/likes. It's a very well done vid as is your implementation of the trombone which is a credit to you. Must be the cleanest implementation I've seen! Please be honored that I'll copy your design/method 100%. Hat Tip to you, Sir. I've had some copper pipe laying on the floor for months for the same use and your vid just showed a Cook Book method of getting on with my long delayed project. It should become a Classic! I got sidetracked with an EFHW Inverted EL late last fall and then a nasty incidence with a Snow Blower rendered my 100Ft LMR400 rather usless for the time being. Ouch.... Again, good job and I just subbed. Glad to read that the loop works well. 73 Russ in NH ..

Can I use mla 30 with icf 2010

What a difference !! wow , mag loop are awesome thank's for your vid . 73's

Thank you for posting. I am just contemplating building my first trombone capacitor, and these are great ideas.

Incidentally, I think you're gorgeous.

Really love your song and vid. But you really should pack the ciggies in. Regards from ex smoker Tom.
