Just my idea for winding coils. I use nylon weadeater/ fishing line for spacing with wire and just leave it there and tape the lot together. Works a charm.👍

You did a nice job making the coil. Well done. Since the SWR is 2 to 1 on 160 meters, you may want to put an antenna analyzer at the base of the antenna and check it there. I was involved in the placement of numerous inverted L's for 80 and 160 meters. We found the feed point impedance to be very close to 20 ohms. I built a 22.22 to 50 ohm UnUn, placed it at the base of each inverted L and now they are have a perfect 1 to 1 match. Nice job on your antenna. I hope you work a lot of DX with it. Barry, KU3X

Honestly when I build coils a lot of the time I will just cheat... And I'll use a tap connected to an alligator clip and this lets me figure out where it needs to go Then I can also adjust it for the top end of the band or the bottom end of the band

DX10 is copper no added steel, check out www.m0mcx.co.uk.

As you know I took a different approach to the same scenario, at the end of my inverted L section I have a trap followed by nearly 20m of wire, of course on 160m the horizontal section being low to the ground does drop the impedance. On the positive it does work and does not significantly affect my 80m band (or the others), it looks like I can gain 60m too. Good to see your coils, a fairly similar process to my coax trap. 73

I would have to almost double the coil size if I put it on the end of the antenna....

I did make a coil to put my 40m vertical on 80m , and it tuned nicely, but after comparing it to a 80m inverted L, I was about 2 s-points down into eu from zl, when using the coil. maybe the losses are expected with a coil.

Hi Mike, Great video as usual. You make this look so easy, but I missed the calculations & apps that you were using for the coils. Now please correct me if I'm wrong, but you appear to be going into Variable Capacitor Production. If so, I could be interested in 1 or 2 of them with the motors on them, depending on price. I follow most (if not all) of your building projects for Amateur Radio. My main interest is in making 1 or 2 multi band Mag Loops in order to cover most (preferably All) of the HF Amateur bands. Mag loops due to very bad noise floor where I live. I do have a DX Commander Classic, but I am unable to put it together & install it by myself due to being disabled. I'm sure there will be someone not too far from me in Sittingbourne, Kent, who will be able to offer me some help with it soon. I also have at my disposal, a 12 foot steel ring, the remains of a 12 foot trampoline, which I am torn between what to do with it. Turn it into a Mag Loop Aerial, or use it as part of the ground radial system with the DX Commander Classic, in the center of it. I don't have space for 360degrees of full length radials, but I have been told that, that dose not matter, as long as I can still get plenty of radials laid out for the DXC. Back to the Mag Loop, This is where my main interest lies, but the problem being the variable capacitor capable of handling the high voltage when running 400 Watts into the mag loop.? ? ? Can you please Help, as I do Not have the tools or skills required to make my own? Many Thanks In Advance, Kind Regards, Ray. AKA M0RAY,

Are you mad??? 400W into a mag loop!!! Do you want to transmit radio signals or cook a full Sunday roast with it??? You can travel the world and some with 10-15W on a decent mag loop. Plus if you are sat anywhere near a mag loop running at 400W you could easily be a cancer victim within a very short period of time. Prey tell,,,,,, how much did your full licence cost you???? P S. You were robbed !!👎😖👎 Have you not seen,,,, there is a video of a guy from USA that had a mag loop on a back pack. He used to push 200W through it. Now, whenever he keys up his 5W QRP set he pisses himself and forgets who he is for about 30 mins. Some people should not be left unsupervised,,,, no matter how old they are !!! 🇬🇧👍🤫👍🇬🇧

Hi Barry, No mate, i'm not mad. that was a typo. It was meant to be 40 Watts, even though that's still on the high side for a mag loop. I've worked VK from the UK with 3 Watts into a Mag Loop quite a few yrs ago , the loop being a special event club field construction project at the time, made from copper pipe. I've been licensed for over 32 yrs, and not had the best of luck in the last 12 months, due to my main antenna having to be pulled down due to age decay. It was a sort of a cross between a G5RG, & a Doublet, Home brew, which worked well considering its orientation. I would Love to have a couple of decent Home Brew Mag Loops in the garden to cover most HF bands as I previously mentioned, but at the moment I don't have the capability to make any. I do have a new replacement home brew center fed wire antenna to go up as soon as I can find someone to get up on my roof to help me install the roof top end of it properly. The other end of it rests on a fiber Glass pole mounted on top of a scaffolding pole which is reasonably manageable to lower and raise by hand. Many Thanks for your reply Barry, Kind Regards, Ray, AKA M0RAY. Sittingbourne, Kent, UK.
