nick: Maybe you are one of those who simply gets 'too much' signal, which can cause freeze-ups due to overloading! 85% is the max signal strength recommended for HD. Richard, Norwich.

thanks, Richard, but would think if that were so it would be all the time, whereas my problem is weather related, and the signal and quality drop to zero.

nick: Having too much signal can cause the tuner to become overloaded and appear to have no signal. If you are seeing 100% during normal conditions then you already have the maximum amount of signal the tuner can handle. Try fitting an attenuator such as one from the link below to reduce the amount of signal reaching the tuner. There are also 6db, 9db and 12db versions which can be connected together in any combination to reduce the signal further if required. I have a 3db connected to my main TV which has successfully stopped breakup I was experiencing on some of the HD channels.

Unfortunately it is only for the duration of the Olympics, and takes the place of CBBC HD : it will disappear again in a couple of weeks.

Steve,

I had to go to this large aerial in order to get the muxes on c56, 58 and particularly 60. If I now attenuate, will lose them. C60 was so difficult to get. I had to remove the wall plate and wire coax direct from the booster on the aerial straight in the back of the set.
I do in fact have four aerials and 4 tvs, three of those aerials are lower down, therefore with lower signal, and all do precisely the same thing.

nick: Hi, Nick. As you've stated that channel 60 was particularly difficult, I suspect you may well need a 4Gfilter. You can get one entirely free of charge from the organisation that is out there to prevent tv viewers from getting tv interference from 4G 'phone masts. Here is its web address:-

at800 | 4G & Freeview | 4G interference | 4G Filters | 800 MHz

Hope this helps, Richard, Norwich. Tuesday, 9th. August, 2016.

Hi.nick,try inverting the aerial upwards as sometimes the signals suffer from being twisted and the signal
moves between the horizontal and vertical ,try an aerial at ground level
