Great work ! The bands in NY,USA has been great ! I even got a NY to England on CB . Just a piece of Coax up to meter pole. T2LT antenna I made for a friend. Was tuning and testing it. Great band with and low 1.1 SWR on EU CB band and like 1.4 SWR on CH 40 of the UK CB band, Just cut a piece of RG 8X and made a antenna out of it. Friend has it now. Loves the tune I got . Cheers from NY !
Hello Lord Callum: I just love the way you explain your designs. Are you shure you weren't previously an auto mechanic. The way you work those spaner wrenches is amusing. On a serious note I love the way your designs go from the computer into your antenna testing field. For me sir the farmers animals in his field is so relaxing. Outside of the plane traffic it's quite peaceful so you can concentrate on your work. God Bless Callum, & my best wishes to Wendy and the dogs. TMP, Unit 22 from N.J.
Hi Cal, That was an Airbus 380. Can't mistake the shape of that fuselage. Now that you will have a 20m yagi up soon, I'm off the air since I had to sell my FTdx10. 😞 I do have a Flex 1500 around here, but that is only 5W output. Will have to make due until my finances get back to normal. I'm praying I won't have to sell my home. You and the family stay safe. 73 WJ3U
Tell her that we are paying for it! Lol. Seriously I would put down a deposit if it would help. I really want a 10m above the ground for my new property in the country.
This is getting close to an idea I had, which was a multi-band T2LT flowerpot antenna. I've mentioned it to Tim before. Basically I was looking at creating a T2LT, but then making it into a fan dipole. I was going to try an upper and lower leg dipole connected in the middle, but I had thought the same as you, just use the same bottom leg and take the impedance hit in having it a bit off-centre fed. Another idea I thought of was the same as yours, but having three different tuned radials for the three bands. I had this thought as the V2000 has a 6m tuned radial on top of 2m and 70cm, and there's that discone that has multiple elements tuned for different bands. Now you have a hinge, maybe you could experiment with the three different sized radials to see how it compares in terms of VSWR.
Interesting - Perhaps a Signature 9 built on top of some spacer poles, or using the top portion of a Signature 18 but including tuned multi-band grounds perhaps using something like rotator cabling? Could be draped on supporting guy cables - that would give multi band high performance in a small garden (back yard here over that puddle) feasibility? I use old rotator cable for tuned "radials" on my ancient Hy-Gain 18AVT/WB-S 5btv (sixties vintage) which would work much better raised at least a couple yards (meters) or so - but I would think a Sig-9 up about 3 meters using a 12.4's the main pole would be even better - (no loss from traps) and still give 6-40 meters coverage.
That mostly full antenna field is amazing. The projects are coming along nicely. I know the planes annoy you but they don't come through on the video as very loud.
Yes, luckily I have discovered a special effect in Davinci Resolve which is essentially AI and I can remove 100% background noise. I don't - I leave it just so.. But that's an easy fix most recently!
Callum always comes across as such a nice and cheerful guy, that it's nice to see him complain about the airplanes. It shows he's as close to human as ham radio operators can get!
