Aerial: 8 el yagi in the roofspace, into a multiswitch feeding 6 apartments.
I am on the top floor about 15m asl
Divis at 34km los:
The 100kW muxes are showing signal "strength" of 10.
The 50kW muxes are showing 9.
Mux 36, listed as being 5kW is showing 5.
Mux 55, listed as being 12kW is showing 7.
Black Mountain at 33km los:
Mux 33, listed as 2kW is giving 7. It must be a lot more than 2kW.
This is a rebroadcast of four RTE channels, programmes ar often not available due to broadcasting rights.
The figures are from my Panasonic DVR, which shows signal strength of 0 to 10, an arbitary figure.
RTE from Claremont Carn at 55km gives a useable signal on Mux 42 and 45 using a 14 ele Log Periodic on my balcony. Saorview shows TV channel numbers in the 800 series on my Freeview tuner - to avoid confusion with the Freeview.

Well what can I say, except to update you on some of the information that's not been updated on this site -
Divis, Local mux on C36, power was increased to 10kW when it moved from C30 on 4th Sept.2019.
Divis, COM7 on C55, power changed to 8.9kW when it moved from C51 on 4th March 2020.
Black Mountain, NIMM on C33, power increased to 3kW when it moved from C39 on 4th Sept.2019.
The reason that the NIMM on C33 gets to you with such a good signal is that it's modulation is the more resilient QPSK (which some say is the equivalent of 10x that using 64QAM) but doesn't have the bandwidth.
