Ok so maybe my explanation is not great but it's good enough to understand roughly what's going on, if you want to know exactly how it works then go get a physics degree :)
Great antenna, so easy to make. Tim inspired me to build one about three years ago and it works fine (been outside all that time). I'm going to make one for 15m now.
The wannabe know it all clowns on the forum they're telling everyone all you need is a current balun of five turns - lol . I went ahead and built one with five turns and what a fuster cluck! Not just the high SWR but variable! LOL and lots of RF in the shack not to mention poor performance in that I was hitting locals a lot weaker than the normal signal strength they knew well. . So I went ahead and wrapped a 16 turn voltage choke instead of a current choke and the thing snapped right in, kind of blew my mind at how broadbanded and how low the SWR is not just in on 11m but also up on 10m! Thanks for a good video 👊🤠
I've got one of these as my portable 2 metre antenna (although I prefer a ladder line Slim Jim) and I have two hanging in a tree for 6 and 4 metres. Easy to make (RG58!) they should really be more popular.
It looks very like an off centre fed dipole considering that the radiating element is almost twice the length of the other leg. The balun is only an isolater and not part of overall antenna length.
QRP700 - from the center up should be about the same as from the center down to the choke, obviously the center being the point where it's cut so the two legs if you will are approximately the same although you may have to trim the top on a bit due to end effect, but as odd as it seems that does not always come into play in my antenna building. 73
I've built one for 15m and I am using it on a 12m (40ft) telescopic mast. Works fine! 🙂 As a newbie I do not have much experience, however it seems to me like there is no simpler way to get on the air and to do DX QSOs.
hennero.3826 - well if it's a half wave on 15 m then it's probably about a 5/8 on 12 which should work great with maybe 2.5 to 1 SWR and if you have a built-in tuner it should handle that okay.
I built one for 10m, then tested it back to back with a shop bought 1/2 wave vertical, both at the same height....... The T2LT was just as good on both RX and TX, since then I've built them for 6m and 2m, great for /P!........ M0KED.

Built them for 2M 10/11M and 20M all worked well for pennies
