Hi, I have just moved to Upavon. Why are we limited here in the Freeview Channels available? eg Why no ITV3? Are there any plans for expansion?
Thanks

Virginia Thorne: Upavon is one of 1000 or so small Public Service only transmitters. The other services are run by the Commercial broadcasters who decide where they wish to place their transmitters. They cover 90% of the population using 80 of the biggest (by population) transmitters. For them to transmit from other transmitter sites, it would roughly double their cost. They declined to increase their coverage.

For a fuller explanation, see here:

Will there ever be more services on the Freeview Light transmitters? | ukfree.tv - independent free digital TV advice


However, I tried an Upavon post code in the Digital UK Tradeview predictor (predicts coverage of transmitters) and there may the possibility that you are on the fringes of Rowridge which is on the Isle of Wight and serves a large area, much of it being on the mainland. It would depend on exactly where you are.

I have spotted one or two aerials on Rowridge in Upavon by looking at Google Streetview. This rather confirms that it might be a possibility to receive from it. Rowridge broadcasts Meridian whereas Upavon relays Mendip which is West region.

It is possible to combine two aerials on different transmitters, however, in this case the channels (frequencies) used by Rowridge and Upavon don't permit this.

However, they are both in the same direction (to within a couple of degrees) from your location and come 18th April the Commercial channels from Rowridge (those that aren't transmitted by Upavon) will be on full power vertically. Before switchover Rowridge's signals were only horizontally polarised, meaning that aerials needed to be horizontal. After switchover it transmits both horizontally and vertically, the Commercial channels being stronger in the latter. As Upavon is vertically polarised, a single vertically polarised aerial may work for both.

In the first instance, you should try manually tuning to UHF channels 25, 22 and 28 on 18th April. These are the three channels of Rowridge's Commercial services and they will come on high power on that date.

I must warn you that there are a few possible stumbling blocks that I can think of:

1. There are some PVRs that don't work too well where they have some channels from one transmitter and some from another. It's therefore not a problem if you don't record the channels.

2. You may need your aerial replacing for one that is sensitive enough to pick-up (or "hear") the weaker Rowridge signals.

3. There may, coming down your aerial lead, be a disparity between the strength of the Upavon signals and the Rowridge ones; the former may be much stronger. The strength of Upavon's signals *may* result in reducted sensitivity of your receiver which in turn makes it more difficult (or problematic) receiving Rowridge's.

This is akin to a bright light with a much dimmer one next to it. The bright light (e.g. a car headlight) makes one's eyes less sensitive to light and hence less sensitive to the already dim light.


As I say, these are possibilities. I would certainly hold out a little hope of more channels come 18th April.

on mon/tues last we lost local signal on our two vodaphone pay as you go mobile phones. reason given by vodaphone was old sim cards and upgrade for g4. phones now operative with new cards locally. assurances need to be given that g4 change is not going to reduce our 100 per cent reception of digi/hd tv from the upavon transmitter????
