Dual 160/80 m Vertical Trap T
Beware - recent results suggest this trap may not be up to high power, at least after some wet weathering. It might be okay if weather-sealed better. YMMV

Okay, Just One More 6 Meter Light Yagi for DE and RI - 5 Elements
A 6 m antenna modeled on A505S. Measurements on my smallish test range suggest this antenna has 14 dB F/B, 30 dB F/Side and AZ pattern falls off 10dB at 45 degrees which is close to the EZNEC model. The 6 m 5 el Yagi found DE and RI in 2020 and VT in 2021 to finish off that band for all LoTW and all FT8. This antenna is now being retired with honors.
Beyond that, between seasons 160, 80, 40, 30, 20, 17, 15, 12 and 10 were all also done so now have 10Band WAS all LoTW/FT8.
