[1000mp] which grounding is better?

Each piece of equipment should have it's own ground strap ...

Problem happen at high power only? <or maybe just detected at HP>

The 'clue' about the varies with the direction of the antenna is also
interesting ... so the problem is on 20/15/10 ? <one or all three?>

Each coax from each amp here has 6 LARGE ferrite beads on it, just
after the low pass filter ... doing that years ago resolved misc. RF issues,
along with grounding the equipment <each with it's own lead> to a single
point ground plate ... <lots of Polyphaser stuff here and a major effort to
do grounding right after losing the entire station in 1995 to a BIG ZAP>

Wait I know ...

UPS your amp HERE ... and see if the RF problem THERE goes away?

B-) ... just trying to 'help' ...
