Since about 1838z I have been using the strapped feeders to my triband VHF/UHF vertical and halo as my 472kHz antenna.

472kHz WSPR unique spots (of me) so far this summer |
Antenna is
higher than the Par triband HF antenna with strapped feeder but the antenna current is
about the same. If the effective height is a bit higher (it should be) then ERP should be higher too. Initial results suggest in some directions it is
down on the earth-electrode antenna but I do seem to be getting
more spots at each transmission than on the earth-electrode or Par antennas.
G4VJF(151km) is a totally new reporter tonight bringing the number of spots of my 472kHz WSPR this summer up to 16 now.
UPDATE 2032z: 29 active stations on 472kHz this evening.
UPDATE 2044z: Now 34 active stations on 472kHz.
UPDATE 2055z: Currently getting about 4 spots per transmission on 472kHz.
UPDATE 2145z: Now 38 active stations on 472kHz. Will leave 472kHz WSPR running through the night to see how latest (compromise) antenna performs.

It's definitely down by 2-3 dB in my direction.
Thanks David. Overall, I get better results on the latest antenna, which is the strapped feeders to the V2000 and 2m halo. G3WCB is definitely stronger on the earth-electrode antenna - I guess he is off the end of the "loop".
Measured strength here no different, but empirically, your the only station i'm still spotting now (07:34)
I do seem to capture you earlier, and lose you later, with each further day.
