80m 7-band off-center-fed dipole bought from gniklat1 on eBay.
Advertised to work on 80m, 40m, 20m, 17m, 12m, 10m, and 6m (tuner needed to cover all of 80m and 10m), with max power 300W PEP, 150W CW, 75W Digital. Advertised to work best in an inverted V configuration with the center at 25-30ft and ends at 8-10ft above ground.

Measurements
Initial SWR measurements, 2020-09-21
From shack
Under antenna, with coax segment 1
After raising long end to ~8ft, 2020-09-23
Under antenna, with coax segment 1
- red = straight
- blue = with hand on coax ring
From shack
(Better on 2m than most of the bands it's supposed to work on...)
After raising rope on long end another ~5ft, 2020-10-06
The center is maybe a foot (or two??) higher than previously.
