The loop tends to null out signals that are perpendicular to it, so it is possible that you could have had an even better RX on some of those weaker ones by rotating it.
Colin, Thanks for another great video! I probably don’t need the loop because I am in a low noise area here in rural South Carolina. But thanks for the link to the George Smart page. Wow! What great collection of resources and fun stuff. I saved the link in my ham radio favorites. 73 and Happy Christmas de N9XY Michael.
Thanks Michael, been a crazy year with the day job. Not much radio time. This will help me enjoy the lower bands at night when I have some spare time. Cheers 👍
Nice example and demonstration of loop Colin!!! Simple, effective, cheap and affordable antenna to any ham with skillful hands!! As I start 40 years ago, (preferebly monoband loop) still amaze me during TX & RX. 👍73,S51X
Great results shown there. I suppose that I am lucky that I don't have much around me in respect to anything that can produce noise, and of course hope it stays that way.
Well done Colin. You're not the first person to crash a website 😂 🙈 Great A/B test. I've gone from a long wire to a multi band delta loop at home, where I'm surrounded by telephone and electric poles. Made a huge difference on receive. My old ft-847 only has one HF antenna connection though.
I built a 900 foot long Beverage receive-only antenna for use on 40, 80, and 160 meters. It turned out to be very good at resisting corona discharge during a thunderstorm that rendered a 40m Yagi useless on receive. Signal levels were lower than on the Yagi, but corona noise was eliminated.
I built a mag loop about 6 months ago, my off center fed dipole, runs a noise floor of about S 7-S10, I can't remember exactly what the noise floor was on the loop was, but it was much less than the OCFD, it tunes from 40 to 15 meters. This was a good video for those looking to try one thank you Colin. 73's🎙KD9OAM🎧
@@MM0OPXFieldRadio I can testify to that. The one I built out of 3/4 copper sent a 20watt FT8 signal heard all over the country, from the basement, it has a very high Q, I'm in the process of building another, to cover more bands, thank you again for your work, to encourage more experimentation. 73's🎙KD9OAM
Well done colinn, ive always used a vert on tx, and 40m dipole 3m high for rx, no noise now. One ant socket on the rig, no probs, made a tx/rx ant switch, works great. 73 mate.
Very good. I suffered from broadband internet noise from my telephone wire (not in use) which Ofcom investigated and said it had probably corroded and radiating.for many years and h.f. was killed for me with S8 noise 160m to 20m except 60m. I lengthened my 40m inverted vee for 60m. I made an indoor magnetic loop to null out the noise and that worked for me. The noise went down considerably when it was changed to fibre optic cable. G4GHB.
I’ve been using a Wellbrook loop for years and on 60m it has been a godsend. I have some noise on 40m but the s/n is night and day over a wire antenna. Ideally you need a radio with a dedicated RX ant port. Loops in general are quieter than Marconi antennae.
@@MM0OPXFieldRadio I think that all new radio's should be fitted with a dedicated RX port. It was a huge part of my dismissing a lot of Icom radio's out of my buying equation. I wasn't keen on the 101 so ended up going for a second-hand TS-990.
I have a S3 or 6 noise depending on the band and etc. I have been looking for a receiver loop and my K4 has. Receive antenna input. Noting is perfect but hearing someone many listening much better.
Build a air choke from coax. 6 meter coax around a botle or whatever. NOT the turns are importent. The 6 meter coax are. You need create reactence. Good Luck. Pa5dek.
Blimey. Maybe I need to get one! I have an MLA 30 on a shortwave receiver I have in my other QTH - hadn't considered using a loop for general 40m receive. What about 80m? My main QTH is very noisy on 80m.
Thats difficult for me to with the space I have here. I recommend you look at the work done by HB9VQQ. He has done many experiments comparing different types.
That website you likend to sucks! Terrible adds that pop up making navigating and reading the site a pain in the ass. Somehow it gets through my NextDNS filter.😡

I have tried but didnt notice much difference so far. I know it has a lot to do with the design of your loop.

Super demonistration of the loop. Working really well. Those clamps for attaching to the mast are very nice. Another great video. Thank you
I forgot I had them but now glad I bought them, 73.

Everything thing Ham looks for 👍

Definitely. A full size antenna in a quiet location will outperform this but no chance here.

I made a tx/rx auto ant switch which will solve your problem.
Excellent Fraser. As Brian says, you need a dedicated swich and you can use different ant's for TX and RX.
@@MM0OPXFieldRadio yeah, I hadn't thought of that. Will look into it.
@@brianfields4479 good idea Brian, cheers.
Hello Colin,
nice to see and hear you again.
Best 73
Thank you Mario. Nice to be posting again.

Awesome! I received an lz1aq loop amplifier and some tubing, just need some time off work to build it.
Its well worth the effort.

is your switch RF sensing or triggered via the rig?
@youtubeaccount931 triggered by the rig
Thanks mate. Thats the plan, get a vertical up for TX now.
Very good.

60m is a killer for me to. I don't use it as my 590 is stil locked. I need to wideband it for this.
Great job as usual Colin! Would be interesting to see if there was any difference whilst rotating the loop
I haven't seen a noticeable difference......yet. watch this space.

@rjy8960 agree but manufacturers see that as people stopping upgrading.
Great video woprks a charm!!!. Where do I buy that strap you have holding the balun to the pole?
Cant remember exactly but you get them from 4x4 / i accessories. They are used to hold the likes of shovels.
I am sure you can also use that new SDR-switch for the same purpose of having a dedicated receive antenna input.
Yes, you can. I will do this when I eventually use a dedicated SRD RX.
wow what a difference. having similar noise problems in vienna.
This or similar is well worth a go then.
I have a S3 or 6 noise depending on the band and etc. I have been looking for a receiver loop and my K4 has. Receive antenna input. Noting is perfect but hearing someone many listening much better.
Agree. This isnt a miracle but helps greatly.
Colin could i enquire where you got the black ratchet clamps you using to fix to the main pole were from please?

@@MM0OPXFieldRadio Thankyou
good video.
is it only for 40 Meter band or does it cover all the HF Band ?
It covers all of HF but best below 20m IMO. It will however depend on your own situation.
✅ well done. 💙
Thank you 😊

I've tried GM3SEK chokes in the past without much luck. These have wayyy more choking.
It's noise on 20-6 that's the issue for me. What's the answer there?
Let me know if you find out. Fortunately those bands are ok for me.
@@MM0OPXFieldRadio at the moment it's DNR on my FTDX10. Which isn't bad to be fair.

It works great on 80m but I didn't show it as I cant do a comparison to a full size antenna. Works well on 160m too.

Thanks Paul. I wonder If I heard you a few nights ago talking to a GW on 40m? Low with me but the loop pulled the signal out.
No not me sadly. I've not been on air for months. Hopefully I will be on over Christmas and New year.
