JOSETTE GERLIER: There have been no technical changes announced for Channel 4 and therefore no need to retune. I've got program data for Friday but I can't see data for any of Channel 4's various channels on Freeview from Saturday onwards. I suspect this is probably just a fault with data supplied by Channel 4 that should be resolved soon.

Some of my channels - for example 10 ITV3 and 20 Drama amongst others - seem to have disappeared over night; I have tried re-tuning but they haven't re-appeared! Have there been some changes ?
Thank you.

Thank you StevensOnln1 for explaining to Mike B what a mains adapter is.
I still have the problem though. I believe it's an aerial connection fault somewhere as the TV is OK on standard but unstable on HD.

Shoreham-by-sea
I am not sure the Freeview antenna solution each house nearby will need will be affordable for our area. I think the mobile network firms will want to offload the risk of poor reception onto local TV antenna firms and households; or push us onto Virgin Media cable, FreeSAT and Sky.
I have been analysing the predicted Freeview Channel List for BN43 5LG and combined that information with transmitter information for Rowridge and Whitehawk transmitters, their polarisations and power levels and signal path lengths given on the terrain diagrams.
To cope with the forthcoming changes I reckon that we will need
(a) 3 antennae, two pointing West and one pointing East as now.
(b) possibly a signal amplifier or two or three
(c) move the antennae outside onto a guyed mast
(d) a signal mixer / bandpass filter arrangement to mix down the antenna feeds into a single cable for distribution to rooms inside the house.
Signal Strength Calculations
#1 Vertical Long Yagi Antenna for Rowridge PSB1, PSB2, PSB3. These output 200kW ERP in Vertical polarisation on UHF C21 to C27. The signal travels over 78km; mainly sea. Signal strength is likely to vary in calm weather due to multipath effects due to reflections off a smooth water surface as the tide rises and falls. The nearby church is likely to attenuate the signal. The increased likelihood of rain suggest an extra 6dB to 12dB margin might be prudent if it does not overload receivers under normal conditions. I tried pointing a loft antenna at Rowridge a long while ago without much luck. Admittedly, I did not try very hard because the Whitehawk signal was easier to make work at that time. The Whitehawk signal reflected off the church nicely too.
#2 Horizontal Long Yagi Antenna and band-filtered masthead amplifier: Rowridge COM7 (24kW), COM8(18kW), LSO(10kW) on UHF C29 to CH37. The signal travels over 78km mainly sea. It is likely to need a 15dB masthead signal booster to raise the signal level to that of PSB1, 2 and 3. The nearby church might attenuate the signal. The increased likelihood of rain suggest an extra 6dB to 12dB margin might be prudent if it does not overload receivers.
#3 Vertical Long Yagi Antenna: Whitehawk COM4, COM5, COM6 (4kW) and LBN (0.4kW). This is about 17dB weaker ERP than Rowridge but much nearer at 12km (equivalent to a 16dB boost). They should be about the same signal strength. My calculation ignored obstacles and the increased likelihood of a lot of rain between here and the Isle of Wight. Some multipath deterioration in signal may be experienced in calm weather when the sea is flat as the tide rises or falls. Some reflection off of other buildings such as the power station chimney may be involved too. So we need to ensure that there is both a good signal quality and a strong signal under normal conditions on all multiplexes.
Weather and Outside Antennas
Our house faces the prevailing SW weather directly off the sea. Most of the year the weather is great; the wind always carries some saltiness and causes rusting. However, often around equinoxes, we get some days with very strong, salty, sandy, wet and gusty gale force winds (G8 to G10 Beaufort). Any outside antenna array (3 long yagis at lower end of UHF TV spectrum) and masthead amplifiers and its masting arrangement will be required to handle this weather without causing or suffering damage. Our chimney stack is unlikely to be strong enough on its own.
What do I have now?
Presently, I have a high quality single wideband antennae in the loft pointed at Whitehawk with about 12dB signal boost near the antenna. I get generally good Freeview reception. I had to position the antenna carefully in the loft and adjust the amplifier gain to get the signal up on all channels (lots of trial and error with an antenna signal meter device).
Who is doing the work?
Q1: Who will design and build the new antenna system required?
Local antenna firms have failed to design a successful solution for just Whitehawk. I don't think they have the skills. The previous owner's contractor ended up walking away after repeated calls to fix poor reception. Some TV installation firms I went to plainly don't appear to know what they are talking about - expecting me to swallow nonsense.
I fear we will end up losing, having to find our own solution without reimbursement from the mobile network operators.
Q2: Is setting to work a capable installation going to be covered by the mobile phone operators even if I design and build it?
Q3: If not what might they offer as an alternative? FreeSAT, Virgin cable, Sky subscription for life
Q4: Finally, has anyone asked Eon if they can build and install a Freeview and DAB repeater on the massive Rampion Wind Farm export sub-station? It is being constructed over the course of this year just 8km away from a huge stretch of the south coast and there is a clear line of sight path to Rowridge. Electrical power shouldn't be a problem. Maintenance out at sea might be rather more expensive than a man or woman in a van. But it might remove the need for Whitehawk and a few Freeview local area transmitters.
I hope you can help
Regards
Emma Atkinson

Emma:
I congratulate you on your thoroughness. However, you will not need 3 aerials at all, one log-periodic will suffice. That should be aimed at Whitehawk Hill and not Rowridge. If you look at Coverage Checker - Detailed View you will see that the only transmitter providing reasonably good service at your location is Whitehawk Hill. The other listed are too far away for reliable reception.
The frequency changes planned do not affect the coverage of any transmitter significantly, so by using a good log-periodic will allow reception of all current and foreseeable future transmissions. I doubt you will need an amplifier at only 12km from the transmitter.
COM7 and COM8 are likely to cease when the 700MHz changes take place as they were only ever intended as a temporary solution to limited capacity.
Note that there will be a gradual change from DVB-T transmissions to use DVB-T2 encoding, which is much more efficient in usage of available bandwidth as well as allowing more channels and more HD services. So any equipment used should become Freeview HD certified.
If you were ever to consider a guyed mast for your aerial, you will need to discuss with your local planning authority whether you will need planning consent and/or building regulations approval. Best to ask first.
You should always check the reported signal strengths on your TV. The ideal is between 60% and 85%, less is unreliable and more will cause loss of pictures and/or sound (even though you have a strong signal, it can be too strong).
So the situation is not a complicated as you fear. A single simple log-periodic properly positioned and aimed should be sufficient for your needs. I am assuming you are not on a communal aerial. If you are, the aerial system is entirely a matter for the managing agents of the property.

To assist you we need you to provide a full post code please. There could be many reasons for you not receiving local channels. Please will you check with your neighbours as to whether they are receiving those channels.
