Geoff: Of course the obvious question would be whether or not anyone else in your immediate vicinity is suffering from similar problems?, and although the engineer carried out a comprehensive check within the boundaries of your property, but should it be known that the problem is also suffered by more than yourself then did the engineer have any facilities for carrying out a mobile check? this starting from about 30 yards or so from the boundary.

These type of tests are essential for determining the source of what you are in effect complaining of, that being wideband RF interference.

The other point I wondered about was whether or not this problem is noticed to be affecting FM or DAB reception? should you use either, or is it just restricted to the higher UHF bands?

Hi JB38, you arre absolutely correct, determining whether our neighbours are suffering from the same effects is essential...unfortunately both our immediate neighbours have Sky which I would have in an instant except that we don't have direct line of sight for any satellite installation due to trees! There are a few more properties around us who do have Freeview so I'm going on a mission later on in the week to try and contact all these properties to see if anyone else is suffering. Thanks for your the meantime I think I'll revert to the bottle! This is really getting to me... Soooo frustrating!

Geoff: Yes, I would appreciate an update, as being a long term engineer who when wearing my domestic hat (mostly non-domestic work) gets involved in trouble shooting missions I would be most interested in what you find out.

ITV4, Film4, Yesterday and others have stopped working for me today. A signal test (samsung TV test) shows them fluctuating between 0 and 45 (out of 100 whatevers) and very high bit error rates.

I did a test on BBC1 and that's at signal strength 85. the top of the page says 'no reported problems,' but I think I have found one.

Steve: The "problems" that are reported are those issued by the broadcasting authorities rather than those of viewers.

The Commercial (COM) channels from Rowridge aren't as strong horizontally and this is because they overlap with Stockland Hill and Crystal Palace which uses the same three channels. The weaker signal and high error rate "could" be a symptom of that, the remedy being to switch the aerial to vertical polarisation to take advantage of the stronger COM signals and "rejection" of a co-channel transmitter.

This assumes that you haven't already switched your aerial.

Hi Dave,

I just tested Dave (the TV channel) and that's shows as signal level 80 on the TV; so if I'm reading the above info correctly that's at the same TX power as the chan's I have issues with.

My aerial is an old analogue one, but I live near the coast opposite Rowridge (Stubbington), and thought I may get away with it.

I have to say that your answer confused me a bit: I thought I could only have a horizontal Ae pointed at Rowridge! If you have a sec could you dumb it down just a tad bud?

I could go and buy a digital Ae, but whenever I see them in shops they seem to be wide-band . I guess shops don't like to stock all the different kinds.

Perhaps I'll wait until tomorrow, and if it's not working try a digital Ae.

Hi, I am a approved digital aerial installer in your area.

If you aerial and cabling is of good condition you should be able to turn your aerial from horizontal to virtical which should correct your issues.

The rowridge transmitter now transmits on both horizontal and vertical polarisation.

Its very important the your do not buy nonsense wideband aerials from local diy stores. they can pickup all signals being sent from different transmitters, they also dont perform too well on rowridge.

You should only use a group A aerial on rowridge, this is something you cannot buy in the shop.

If you continue to have issues and want someone credible to do the repairs then my contact details are

Steve: Since the changes in April, Rowridge transmits vertically as well as horizontally.

The PSB (Public Service) channels are 200kW horizontally and 200kW vertically. The COMs are 50kW horizontally and 200kW vertically.

The main reason for the horizontal signals are for backward-compatibility with aerials that are already fitted (horizontally).

I mentioned aerial replacements, but they shouldn't (generally speaking) be needed for Rowridge and a wideband aerial isn't needed. These tend to have less gain on the (lower) channels/frequencies that Rowridge uses so a Group A aerial (the "non-wideband" type you probably have) is the best. Turning it to vertical should do the trick.

Hi Dave and Jamie,

The change to vertical has given me back my channels. Thank you very much for helping.

The signal level for the returned channels is still significantly lower than all the others however: 85 for BBC and just about all that are not on COM6; COM6 only gives me 60 on my TV's strength tester.

I note that COM6 is the highest frequency out of Rowridge and am wondering if my old Ae may not cope due to that.

If it's not my Ae I have to assume that COM6 is indeed low on power at the moment.

Jamie: Cheers for the Ae advice bud; I have looked on Amazon and it's simple for me to order a correct one from there.

Steve: If you are looking for an aerial or information on them, see ATV's site:

Rowridge Transmitter

If there is a good clear path to the transmitter, then the signal could be a bit on the high side. The effect can appear the same as too little a signal:

An attenuator may be useful, e.g. (other suppliers are available):
