Lost RTE1 but have RTE2, Virgin 1 & TG4

It's most likely to be something at your own end alright. Check simple stuff first, like cables & connections near the receiver.

Also check your signal quality/strength readings. This will show if there is any difference before and after any changes you do. A perfect picture could just be a little bit stronger signal than one which gives no picture.

Signal Quality is the key. Check quality readings. RTE1 (Clermont Carn C45) for me has caused issues from time to time.

Aerials generally don't move until they fall down altogether. The fact that you refer to it as 'on the wall' would lead me to believe that it's one of those combined aerial/dish installs, that tend to compromise aerial location for installer convenience &/or cost. It probably never delivered a great signal & something small could have pushed it to the point where mux 2 is now not receivable.

Water getting in is something to look for too; could be evident at the plug on the aerial cable, or you might notice an open or missing cap on the aerial connection box.

I have an indoor aerial in the bedroom and can pick up Saorview from Three Rock but I often lose RTE1. I'm pretty sure it's because the RTE1 mux is just ouside the optimal frequency range for the aerial and atmospheric conditions because on good days I get a perfect HD picture on RTE1, other days nothing. Lots of other posters on different threads have reported similar issues when they have marginal reception and/or were using an indoor aerial.

Are all indoor aerials not wideband?

You'd expect so but what else could be causing my aerial to fail to pick up the RTE1 mux from Three Rock on some days and give me a perfect HD picture on others?

I tried out saorview using a rabbits ears and as you say RTE1 was always tricky, I'm on mount Leinster.

Unlike the analogue days when a weak signal gradually faded away into snow, a digital signal is all or nothing. It's quit possible to have a 'perfect picture' on one mux which is just above the threshold and none on the other which is just below. This sometimes referred to as 'the digital cliff'.
