TIM wardlaw: I think the best course of action to "hopefully" get good reception for COM4-6 is to switch to vertical polarity, this if you haven't already done so. The word "hopefully" is in quotes because with reception issues there is never a guarantee, and that in this instance it would seem reasonable to conclude that the higher-power VP signals may solve the issue.
Looking back at earlier postings, you have spoken on the saga of Rowridge HP versus VP. Since COM7 and COM8 were turned off, there is no longer any HP-only multiplex, with the exception of the Southampton Local TV one, broadcast in the direction of Southampton.
You have previously given your location as New Milton, and the Freeview Detailed Coverage Checker does not even suggest the Southampton Local TV multiplex as a possibility for your postcode, hence why I suggest it is probably and open and shut case for switching to VP where HP is not satisfactory.
Rowridge, uniquely, broadcasts with both horizontal and vertical polarity, having done so since digital switchover in 2012. PSB1-3 are 200kW HP and 200kW VP. COM4-6 are 50kW HP and 200kW VP.
It occurred to me at switchover that Rowridge had effectively become VP, with the HP transmissions more for legacy purposes, to serve those whose aerials had not been reoriented from horizontal. Subsequently, of course, the HP-only multiplexes of COM7, COM8 and Southampton Local TV threw a spanner in the works, creating a dog's dinner whereby some viewers would have faced the choice of switching back to HP, and possibly having to sacrifice good reception on one or multiplexes to benefit on one or more others.
The power of 50kW for COM4-6 is in no way "low", many main transmitters not even reaching such. Being so close to the transmitter as you are, I wonder if the trees in your vicinity in the direction of the transmitter are shadowing the signal for you, hence poor or variable reception.
The most likely reason for the lower power HP COMs at Rowridge is because they are co-channel with the COMs of Stockland Hill and Crystal Palace (both which broadcast only HP). The PSBs of Rowridge with these two transmitters are not co-channel.

Is this engineering work the cause of occasional short-lived dropouts on PSB3 channels from Rowridge with a black screen and a 'no signal' message? I usually get a strong signal so these dropouts are an unpleasant surprise.

R Murchie:
As the report says "pixellation or flickering on some or all channels", so that is highly probable.
If the "flickering" is a brief drop in signal, then getting a no signal message wouldn't be unexpected.
