Concerning mains earth for the TX antenna: Exactly the same here. I

counterpoise (difference: 0.something A versus 1.9 A antenna current)
Hi Joe ,
The capture I sent with my last mail was timed 04:00 UTC on the 8th July.
By the way, I belive that the mains earth is the best available since
it extends for many yards,even miles, from the antenna site.In a built
up area it will extend all round the antenna. It certainly is the best
for me, much more current than all my radials put together.
But a totally different story for RX: I use a large relay contact to
OPEN the connection between "mains earth" and "antenna earth" during
reception, because the mains earth is terribly noise-polluted.
