    http://www.radiokerry.ie/saorview-customers-advised-not-use-amplifiers-solution-signal-interference/

    Mr Higgins of Saorview suggests "interference from abroad", due to weather conditions but I fail to see how likely a possibility that is in Rathmore Co. Kerry, which is also just approx 10km from Mullaghanish transmitter

    Also an amplifier would not make any (co-channel) interference from a distant transmitter on the same UHF channel any worse (or any better). The dB difference between them will remain the same.
    (though obviously people are well aware of difficulties with many amplifiers if there is strong pick up of TETRA, mobile base stations etc causing overload, and trying a more directional aerial would be the correct route if co-channel interference was the issue - provided its not from the same direction!).

    He rightly says that customers cabling/aerials need to be in good condition


    If there is an external issue affecting reception of viewers in areas around Rathmore, I would question if windfarms are the cause. The turbines also swivel about depending which way the wind is blowing, this can cause reception issues to come and go, which may wrongly lead to the belief it is due to "'high pressure" etc if its only happening sometimes.

    PS there was also a longer interview (Saorview and Saorsat as well), though the link to it currently has wrong audio, maybe it will be fixed:

    The main issue with reception in Rathmore is that there is a mountain range between the town and Mullaghanish which blocks reception for some and heavily weakens it for others.

    Analogue TV3/TG4 reception was very difficult in the area due to severe multipath on the signal. A large proportion of viewers in the area were using aerial setups in the 90s which consisted of a VHF Band III pointed at Mullaghanish diplexed with a UHF Group A pointed at the nearby deflector in Knocknagree, and TV3 & TG4 which launched later were being received off the back of these aerials. The fact that the deflector (23, 26, 30, 33) were adjacent to the Irish channels (27 & 31) didn't help either.
