The televes 45HD aerial does loop through without the 12v supply, tried this on a tempoary basis direct to one tv & the aerial pointing towards the transmitter through a velux window, seemed to be ok.
There's no switch on the distribution amplifier to cut off the supply, so back to the old drawing board. Since the master head amplifier is situated nest to the dipole a straight connection to the aerial is not an option.
Thanks

I'm at LS17 9LP (Yorkshire). We've had digital for 3 or 4 years, and have recently got 2 issues. They have happened since I followed the on- screen instructions to re tune after 20th August.
Firstly - the digital signal fluctuates during the afternoon. From midday until around 8pm, we get breakup or even total loss on all channels. Reception is perfectly good the rest of the time.
Secondly, since we retuned, our "local" news on BBC (channel 1) seems to think we live in Lincolnshire. To get the Yorkshire news, we have to tune to channel 825
We have a wideband amplified aerial mounted on the wall of the house, horizontally aligned pointing at 194 degrees (to Emley Moor) direct into a sky box. The signal goes from there into a 4 way splitter for distribution to sets around the house. This configuration allows sky to also be distributed on analogue.
Any ideas why we get this fluctuation, and why the locality has changed?
