Un-boxing and initial installation of a Tune-A-Tenna for #AmateurRadio #HamRadio

The Tune-A-Tenna is an Inverted Vee dipole HF antenna, the length of which can be remotely adjusted to a resonant length, so you can operate QRO (i.e. full legal limit of 1500 watts) without a trans-match (aka "tuner").

This ingenious antenna system can generally get down to a 1:1 SWR, or very near to it. Low SWR means less loss in the coax, higher effective radiated power, better signal reports, pile-up busting, improved fuel mileage, and world peace. (No guarantee of fuel mileage expressed or implied.)

Oh, sure, it’s supposed to be a bit informative... but mostly this is a bumbling nerd on the roof. Speaking of which, after I got this up on the mast-mounted adjacent to the roof, I did the calculations seen on page 26 of https://docs.fcc.gov/public/attachmen... and determined that to remain MPE compliant, I could only operate barefoot, but not QRO, if my wife was in her office.

I also could not quite get down to all of the 80-meter band (could get some of 75 meters, but not optimal tune), due to the size of my lot. So I've since moved it to a separate 50' carbon fiber mast, not adjacent to the house, with the elements angled at less than 180 degrees from each other. (I hope to make another video showing the modeling of this leaning inverted vee, but the short story is it works just fine.)
