I was testing the aerial and earth with a HMV 1107 last night, I also connected up the Global AT2000 coupler.
The new RF earth does make a distinct improvement to the signal, but not quite as much as the earth from the CH radiator, (mains earth).
The ATU peaks up nicely on the HF end of MW and even better on the SW band, making a big difference to the quality and strength of the signal when compared to if it is switched to "through".
The new setup all works well with a valve radio designed for a long wire aerial, but although the new aerial does boost the signal with a transistor radio with AM aerial sockets, (Philips D2935 https://www.radiomuseum.org/r/philips_d_2935_d2935.html ) the ATU seems to have little effect.
Oddly, the HMV 1107 struggles to receive Gold on 1548kHz even with the new aerial, yet my Hacker RP25A has no problem on just its ferrite rod.
I need to test a few of my KB radios, but they are all downstairs at the moment, and I pulled my back a little raising the new mast up, so that will waite a while till it feels better.
So far in my tests the wanted signals are swamping any unwanted interference, but then I still have the scart to RF converter, which was the main cause of interference, unplugged.
