My aerial is on the roof, looking right across the Gordano Valley. Aerial ws erected about 18 months ago. I have checked the junction inside the roof also and it appears okay. There is another television upstairs in the back of the house, with an integral digibox, this is receiving okay. Even my 8 year old grand daughter can't solve problem!! Advice would be appreciated!

C Lewis: Mendip would appear as your best bet for reception, however maybe you could indicate what the nature of your problem actually is?

This being requested as you are only indicating as having made one posting, and so no checking back can be made.

Just moved into BS20 7HU and the house doesn't have an aerial! The chap I bought from said this postcode won't pick up any station. I don't believe him! I think he's lived in the area for 10 years and not tried an aerial since the digital switchover and any upgrades made in the area. Do you think I'm right?

Pongo: Take a walk around the area and see what transmitters the other houses are using.

Any prediction or suggestion made here would need investigating as only when an installer is on site can confirmation be given that it is possible to receive from a particular station. Local obstructions can affect what can be picked up.

Digital UK Tradeview predictor suggests you might have excellent reception from Portishead relay transmitter. However, it is a Freeview Light transmitter, carrying Public Service Broadcaster (PSB) channels only. These being BBC TV and radio, ITV1, ITV1+1, ITV2, Channel 4, Channel 4+1, E4, More 4, Channel 5 and the four HD channels.

It would appear that reception from Mendip is out of the question.

The predictor says of reception from Bristol Kings Western, "good" on some channels and "variable" on others. I wouldn't be too concerned about the latter; what an installer finds when on site is what matters. Bristol Kings Western is a full Freeview transmitter and therefore carries the Commercial (COM) channels as well as the PSBs. It is a relay of Mendip (as is Portishead) and therefore carries the same regional programming.

You are predicted as being able to get excellent reception from Wenvoe. It too is a full Freeview transmitter but it carries Wales region programmes. The channels used for Wenvoe and Portishead will allow an aerial on each to be combined (diplexed) together into one downlead. You would then be able to watch West programming from Portishead transmitter and receive the COMs from Wenvoe. There are, however, some receivers that don't fair well when picking up some channels from one transmitter and others from another, this being an issue for some recorders that may not record due to this.

If possible, I would say that your first preference must be receiving the full service from Bristol Kings Western.

The Portishead transmitter is on the top of Hanhover House, Friary Road which is at 208 degrees (roughly south south west). Aerials directed at it will be vertical. Bristol Kings Western is at 86 degrees (east) and aerials will also be vertical. Wenvoe is at 265 degrees (west) and aerials will be horizontal.
