I got a new aerial as my signal strength is not the best
So what are the signal strengths and quality as reported by the Humax on the multiplexes you can receive?

I have seen COM 5 as low as 40% in bad weather still 100% quality.

I am surprised that a signal strength of what I guess would be just below 50% with the splitter is not sufficient. In the past I have run for extended periods with signal strength around 30%. Does anyone know if the transmission mode has an effect on the required signal strength?

The splitter does attenuate the signal, which is not too strong IMHO.Looking again at the splitter your are using compared to the one designed for UHF TV 21-68 474-850 Mhz, the one you are using starts at 5 Mhz.
Guessing the one you have is not designed for the job. Either use the one originally linked or change the connectors for the superior F type designs.
It likely has a much larger insertion loss in the TV UHF Band.

The splitter Graham recommended is certainly doing the job for me (he says with fingers tightly crossed) https://www.screwfix.com/p/labgear-19132r-s-2-way-metal-t-splitter/44534
I have just been running a signal test on channel 56 which is the worst performing of all the channels. It's currently down as far as 36% signal strength (and has been all evening) but signal quality is 100%.

Attached the current advert text from Screwfix.
Plug in to 2 sockets out. This is not suitable for the back of a 2000T.

I don't plug it straight into the back of the device. I plug it into the wall socket. It's male into wall socket with two female outs.
I use two made up leads with male co-axial connectors on each end. This is the best results I have had to date. If you need female adapters then they only cost pence to buy. I think Graham posted a link in the other thread.

The existing aerial lead to the Humax should be removed from the Humax and connected to the splitter in. The existing patch lead going to the TV is then removed from the Humax and connected to one of the outputs. A second patch lead connects from the other splitter out to the Humax rf in.

You can't do that with the Screwfix splitter I bought. That splitter input is male, the aerial lead removed from the input of the humax is male, they don't fit without an adaptor. The female outputs on that splitter don't fit with the existing female in patch lead to the TV, or into the humax.
It's an unsuitable splitter for this job.
Other splitters are available, and I have no affiliation with the people that sell them.
