Thanks for getting the polar diagram for Sudbury, shows the big drop in signal for CH37 and CH31 in my direction (CM96HG),
Ties up with the spectrum analyser readings
Pretty hopeless much of the time on those two MUX into the evenings, again matching coverage checker.

Any ideas on why this has happened, and for whose benefit ? It all used to work fine before the 800 and 700 clearances

Yes it is the correct aerial, have tried a couple I can get to both a K (in use now) and a W (replaced an E at the 800 switchover in 2018).
I can also see the power drop from previous spectrum analyser plots of the W that saved off when I aligned using the SA after switching from the E.
C29 is indeed flaky at times too, as the predictor expects.

I am not aware of any C37 blockers, but will check again as that is of course the old RF VCR frequency.

My question was more why has a special radiation pattern been put in now, and how did a change that makes reception worse get permission ?
A coverage map by MUX would be interesting to see.
