Which companies have run the Channel 3 services in the Mendip transmitter area
jb38 After considering using Rowridge horizontal and a very patient aerial installer to improve Com7 a high gain aerial was fitted although this improved reception but during high pressure times lost BBC &ITV so resorted to installing C/D aerial on Poole using Mendip for other channels now have signal strength of 90 quality 100 on all channels on Samsung 80 strength on You View qual 100 but can no longer get Com7 on any set.
The two aerials are connected by di-plexer or filter could this be the cause?
Signals from SW also seem blocked.

Mike: Yes, as each of the two inputs on the diplexer caters for a certain range of frequencies and attenuating any outside of the range, the problem being that COM7 (C33) is not in the range applicable for the reception of Mendips normal transmissions as its in the range used by Rowridge.
Unfortunately diplexer's cannot be used in situations such as this, the only option being to run individual cables from each of the two aerials.

Mike: In that case, then there is no reason why you cannot receive Mendip's COM7, that is unless the signal level received on C33 is that low that the slight loss introduced by the diplexer is enough to cause it to drop under the threshold for reception.
Of course DUK's reception predictor does not indicate that you can receive any signal from the COM7 transmitter at your location, although the predictor might not have been updated since COM7 increased in power from 17.5 Kw up to the level presently indicated of 72.35Kw compared to the six other Muxes on 100Kw, 72.35Kw not being exactly low powered compared to the differential on some other main stations, e.g: Rowridges (H) PSB's on 200Kw whereas its COM7 is only on 24.41Kw. References to power outputs taken from that indicated by DUK.
On the subject of the diplexer, hindsight is a great thing! insomuch that it might have been better if the aerial installer had just fitted an aerial combiner rather than diplexer, as then the only attenuation would have been the slight insertion loss as the signals passed though the device rather than on each of the two group determined inputs.

One possible solution that might be worth considering is the use of a coaxial switch. That will allow the siognals from both sources to be selected and fed to the euipment without significant reduction - but at the penalty of having to operate the switch to connect to the different source.
I used that method when I lived in Swindon and could get signals from both Mendip and Oxford - but not strongly enough to pass through a diplexer well enough for good reliable results.
