Bob Chapman; The obvious question would be, have you tried another battery? as the frequency used by remote controls is no where near that used by Freeview transmitters.

Pauline Beer: The problem referred to is likely still to be as a result of the continuing high pressure interference that has been plaguing viewers in various Southern areas, as although you reside @ 24 miles away from the Midhurst transmitter in an RH10 location and report problems with your ITV channels, another viewer located in an RH20 location @ 13 miles from the same transmitter posted a comment six minutes earlier to the effect that all his channels were OK except HD.

John Pontet: What you have reported does not suggest to me that the problem is in anyway connected with the transmitter as after all there are six transmitters involved, but is much more likely being caused by exactly the same reason that is responsible for numerous other viewers being plagued, insomuch as the result of the continuing high pressure allowing reception from distant transmitters operating on the same frequencies as used by Hannington and which are corrupting the data stream of the channels from said station thereby killing reception.
Another aspect of your reception from Hannington that wont help the situation is the fact that the signal is partially obstructed at just under 12 miles away, this meaning that reception is via an element of diffraction (signal bending) and with this being something which causes the signal to be more vulnerable to being interfered with.
You can see what I am referring to by opening the link.

Steve: I am located in a position (West side of Stamford) and where I can normally receive transmissions from either Sandy , Waltham or the PSB muxes from Belmont, however on having just carried out a signal check on all three transmitters I was amazed to see that virtually nothing was being received from Sandy nor Belmont as well as two of the commercials (ArqA / ArqB) from Waltham, this strongly suggesting that atmospheric conditions interference of an extremely high level is in force this evening.

liz: If you already have a Sky+HD box then you will have two input cables from the dish and with each being fed from an individual port on the dishes LNB.
However as quad LNB's are generally fitted as standard then this means that you will only be able to use two Freesat TV's in addition to the Sky+ box and achieved by running a feed from each of the TV's back to the spare ports on the LNB, if however you require the third TV to also use Freesat then this will require you to change the quad block over to an "Octo block", the Octo block being an 8 port device in order to cater for the third box and with a feed wire from same being run to the TV in question.
As far as cables are concerned standard grade WF100 coax should be perfect for your requirements, you will of course also require a number of "F" connectors in order to connect the coax into the Freesat TV and also the Octoblock.

liz: With regards to feeding the signal from the Freesat TV into the TV located in another room in a similar way to the method used on Sky boxes, yes, this can be achieved by purchasing an RF modulator such as seen on the undermentioned link, the device being connected into your TV's scart socket, and with the signal passing from same into the modulator which in turn converts it into an analogue RF signal in exactly the same way as a Sky box.
But though, and this is important! you would have to ensure that your Freesat TV is capable of analogue reception otherwise the Sky modulator system would not work, the other point being, that I would prefer if the model number of your intended purchase was known "before" taking any action, as it might just be possible to achieve the desired result without having to purchase an RF modulator.
By the way, the easiest way of determining the number of devices that you can use on a dish system is by first of all having a look at the LNB and counting the number of output ports it offers, remembering that each device being used requires its own individual port except in the case of twin tuner recording devices such as Sky+ or Freesat PVR's (recorders), as by the fact of those devices having twin tuners then this counts as two devices, this of course NOT applying to Freeview via a normal aerial twin tuner devices.

Neil Killip: Although you may well have been informed that Sandy rather than Waltham should provide a better signal at the location given I cant quite understand why, as a terrain prediction from both Waltham and Sandy indicates that the signal path is obstructed from both stations but with Sandy being a tad worse, therefore I can only assume that the Freeview advisor was looking at UK Digital's reception predictor when the statement was made.
Links to all referred to can be seen by opening the undermentioned links, the first being Digital UK's reception prediction.

Gavin: Should your model of TV offer a manual tuning facility then enter and scan C57 which is Oxfords HD channel, if the situation remains the same after having carried the aforementioned out then could you please provide the model number of the device in question.
By the way, when you say that the BT Freeview box can receive HD when plugged into the same aerial, does this refer to viewing an HD channel on the box "immediately" before tuning in your new TV? because if any gap exists between the two then the HD signal may have dropped out due the widespread problems being caused by high pressure interference

John: Well, although I am unable to comment as to any possible reasons for your continuing bad reception by being unaware of your exact locality, a post code or one from somewhere nearby, e.g: a shop / Post office being suffice, I would however fully endorse anyone's decision to opt for Freesat if they have been plagued with reception problems due to the area they happen to reside in as satisfactory reception of digital transmissions can only be achieved via a perfectly stable signal, this in many cases only obtainable via the domain of satellite reception (Sky or Freesat) this mode offering virtually guaranteed reception for around 99.9% of the time, the odd occasion that it might not do being during a heavy thundery type downpour, or maybe on an odd occasion during the winter months when snow has been deposited within the bowl of the dish, a quick swipe across the dish with a light brush instantly rectifying the problem.
Anyway thanks for your update, and should you at any time require further assistance involving such as Freesat or whatever, please do not hesitate to ask.
