Nice job, Ian. New one on me, this. I enjoy using the 10m band, daily with a few local mates. Every now and the we get a break from Europe - it's good fun. Cheers, Mick.
Thanks Mick. Yes I’ve had a bit of European fun myself on 10 with my OCFD, but I wanted something specific to see what’s out there 👍🏻 Had success with the 6m version 😀
Well done Ian. I was talking to guy across the pond about that very antenna for 40m a few months ago. With all those lovely houses around you they are probably the sort who do not like antennas. Sell up and buy a little farm. Next week the the temp will be up the double figures. 73's de ON8EI John.
Thanks John! Yes, going for discretion at this end 😀 Now I know all the dimensions, I’ve made the final version today, so will document and release part 2 👍🏻
Thanks Chris and yes all’s well this end 👍🏻 Ditto your end too? Rebuilt this test design properly yesterday, so now got the final sizes etc. and a deployable yagi 😀
@@ianxfs great, I,ll await vid 2 and then I’ll order the materials . I have loads of tri rated 1.0 and 1.5mm stranded cable so will probably use that. 🙂
Great video Ian. MMANA doesn't consider the velocity factor. I modelled a 20m hexbeam and it was also slightly off. Keep up the good work mate. 73 de Kevin, VK4KK
Enjoyed the video, Ian, and it might just inspire me to try something similar on 6m (I need to review your Mini-Horse video). Thank you for posting and 73! de WX0V
Thanks! Yes, the 6m one works well. Rebuilt the final version of this 10m yesterday so will release part 2 with measurements and quick-build technique etc. 👍🏻 Using the 6m /P in the cold, wet, windy dark on a distant hill somewhere taught me a quick build method which I’m not sure is on those early 6m videos 🤔 Part 2 of this 10m will show the same methods though 👍🏻
Now that is a lot less visible that most aerials. Now do the impossible and make it disappear all together and I might get to sneak it up when no one is looking! A lot wouldn't even realise what it was for. I wonder if I replaced the plastic with thin solid fibreglass rods would I get away with that? Still, those blanks are a bit on the pricey side being solid fibreglass.
Hi Bob! Fibreglass or even long bamboo cane? This is cheap mind and I know it works. Rebuilt the final version yesterday so will release part 2 with measurements and quick-build technique etc. 👍🏻
@@ianxfs Looking forward to it. Better then the big square thing I once built, came crashing down in a gale and I didn't rebuild it. But that was at another house, on an estate. I had a huge aerial up there a while until it bent over in the wind and caught up in some trees at the other end of a square. It was fibreglass, green and very very tall, some sort of co-linier, so you can imagine the size at 27Mhz. I think it was Italian made, but by the time I got it there was no label on it. I thought the chimney was going to come down that night! The saving grace was it bent right over and across the square courtyard and got caught in trees at the other side of the houses. I went looking for it in the morning and thought it had broken when I looked up (it was quite high up) I just saw part of it and as it wasn't in the garden I thought it must have fallen into the square. So I went round to see (expecting to see it sticking out of the ribs of a car) and saw the neighbour standing looking up, I followed his gaze to see the aerial bent right over, crossing the square courtyard, over the top of his house and into the trees beyond. There were cracking noises, bits of twigs, leaves, and all sorts flying off the trees as the aerial was trying to get back to vertical. Then the cracking was followed by a woosh noise and the aerial broke free, showered us with twigs, leaves and a branch was propelled skyward. It came back up with one almighty "Twang" noise and it stood there shaking and vibrating. I thought it was going to break something, but I got away with it. The neighbour turned round to me and just said "I think that aerial is a bit big!" and he calmly walked away into his house. I thought I was in for a tough time, but he was ok with as nothing was damaged. Aerial was down that weekend and gone to a mate who wanted it. He is not on CB now as far as I know, so I have no idea where the aerial is these days. I was given it as it was to big for the person who had it, I gave it away as it was to big for me. I never heard if he kept it, I know he used it as he said the SWR was at its lowest 1.5:1, nothing wrong with that I thought. But he thought it should be a lot lower. But that aerial was a beast, full of coils and spaced turns and it had a transformer of some kind inside a metal bit where it mounted. I can't remember but I think it was supposed to be a 1/4 wave on top of two half waves. So at 11Mtrs, you can imagine its size! It made the Thunderpole look tiny! lol.
@@ianxfs The 2 meter co-liner my mate had looked like a Silver Rod, even the (Now who was it at the time?) DTI can't remember, they went in past one night and they asked what he used the aerial for, he said 2 meters, yeah, they dais, but what do you use the Silver Rod for? He showed them his licence and the kept asking about the Silver Rod. He told them it was a 2 meter co-linier but they pointed to his CB and told him it was a Silver Rod. No, the aerial for it is in the attic. They finally gave up after them saying his 2 meter was in the attic and his CB aerial was outside. He told them to go up and look, but they declined. Just a well, he ad a 1/4 wave 102" aerial sticking out the top of his roof. Twice as long as he was allowed lol.
hi thanks to your cool self build im starting to build your 10mtr moxon today, the only thing im a bit confused about is where and which ends the coal is connected to the different elements could you help me with this please?
Hi Paul. There’s a mk2 video on the channel that shows an easier way to build this short-boom folder 3 element yagi (it’s not a Moxon). If you check out the more recent video it will help. The two centre boom wires are the ones connecting to the coax.
To me I could see the frame being used for a Moxon. Not one Moxon but two or three antennas in the same way as the Cobwebb antenna. Sort of a 6,4,2 and 70cms type of antenna system.
Hi built your antenna ,using your final measurements at 28500 my swr is 2.0 27500=3,,2900=3 roughly,,I cant get the swr to dip at all, any advice please Paul
