my only concern about the swr curves being that GOOD/flat is that it might be partially due to the very thin wire's resistance. It would be interesting to see what the DC resistance is for 30m of this wire before being made into the antenna (the skin effect HF resistance will obviously be higher than this but it is still useful to see). I'm certainly NOT saying that it isn't a useful antenna. I also think mag-loops are great & similarly they are not the highest efficiency but still very useful/usable. The TTFD has a wavelength of low resistance wire in it AND has a big resistor explicitly added and people like it so resistance in antennas isn't always a showstopper. Personally I use the single strand 2mm solid aluminium electric fence wire for antennas but it is a sod for kinking so your woven stuff looks like it might be better for portable deployment.
Yeah, this is mostly for a "when you need it" antenna, it's nothing I'd have up permanently. Fun to experiment though, and thanks for the idea of what to test if I make another one of these some times. Thanks for watching, 73!
I work the world with a 20m delta loop and pskreporter shows I'm heard from both directions on the opposite side of the globe. That is just the furthest distance on the globe from my location, not necessarily the route my signal took. I use a vertical delta loop bottom fed which is 50 Ohms. It throws a very low takeoff angle when the loop is 1 wavelengh high(bottom of loop). That means my antenna has to be nearly 90ft to the top and about 60ft at the bottom. Use 2 of them rotated 1/4 turn and use an antenna switch for a poor mans rotator. Also, they have a very low noise floor.
Would be great to be able to have one of these up permanently (properly made of course), seems like some amazing antennas to have. Thanks for watching!
Cool project beautiful property!
Thanks 🙂
I'd liked the Lake shore!
Good place for anything!
Thanks, it's my family's cabin. Nice place to operate from
Great views!
It's a lovely place to operate from
