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.

Saturday 3 November 2012 7:02PM

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:

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:

I quick final post from me (I hope so anyway).

I just went back and tested all the COM6 channels again, and today they are at 82, pretty much the same as all the others. I think that this means that Rowridge was indeed low on power yesterday when I was only getting 60 after the shift to vertical, and didly horizontal.

I live in North Dorset (DT10) at the edge of Rowridge reception. My aerial is set for horizontal polarisation but I don't know if I can rotate it for vertical. I have another aerial directed at Mendip transmitter, would I create a problem if I rotated this one and aimed it at rowridge thus giving both vertical and horizontal set up at the same time?

Dave Lindsay
Tuesday 6 November 2012 2:55PM

Mike Wells: The Mendip aerial may be a Group C/D one. If it is a wideband aerial, then this will work to a degree for Rowridge. Wideband yagi aerials aren't as good for Group A channels, of which Rowridge uses exclusively:

<img src="" class="xico" style="vertical-align:text-bottom" alt=" link icon"> link iconAerials, TV Aerial and Digital Aerial

It's not possible to receive horizontally and vertically at the same time with a yagi aerial.

Rowridge broadcasts PSBs at 200kW horizontally and vertically. Its COMs are 50kW horizontally and 200kW vertically. The restriction horizontally is primarily due to the overlap with Stockland Hill and Crystal Palace which use the same three channels (but don't share PSB channels).

The Digital UK Postcode Checker suggests "good" reception of Stockland Hill's PSBs and none of its COMs. The same goes for Rowridge for both polarisations. Whilst it should always be born in mind that such predictors are calculated and may not be what is found to be possible, it could suggest that the only transmitter you may pick up the COMs from is Mendip.

It is possible that even though the vertical signals from Rowridge are the same power that they don't serve the same areas because the radiation patterns are different. For example, maybe its COMs are restricted to the south for international reasons. Similarly, maybe they are restricted in the direction of Stockland Hill so as not to interfere. This is possible speculation on my part which may be worth bearing in mind.

Refer to this page:

<img src="" class="xico" style="vertical-align:text-bottom" alt=" link icon"> link iconThe commercial multiplex after switchover: ArqA, ArqB and SDN | - 10 years of independent, free digital TV advice

It shows that around one third of Rowridge viewers are likely to be unable to receive the COMs.

if you change your rowridge aerial to vertical it will not affect your 2nd aerial which is on another transmitter.

Changing the polarisation of the rowridge aerial to VP will only enable to receive the reception with a better signal, the mux's which VP receive are exactly the same as the mux's you are receiving on HP.

The aerial doesnt know its receiving HP or VP so cannot cause issues when combining with your 2nd aerial. It is simply receiving reception from certain mux's which do not conflict with the 2nd aerial.



Mike Wells

To clarify I am thinking of changing the Mendip aerial to point at Rowridge with vertical polarisation thus giving two aerials poiting at the same transmitter with one in vertical plane and one in horizontal plane. I want to maintain reception from Rowridge as that gives us the local news (BBC South) that interests us.

Dave Lindsay
Tuesday 6 November 2012 4:55PM

Mike Wells: As I have explained, the main thing it would depend on is if the Mendip aerial a Group C/D one. If it is then it isn't really suited to a Group A transmitter, which Rowridge is.

You cannot really use two aerials simulataneously, one horizontally and one vertically so I don't understand what you are thinking that will be gained.

There is an element of doubt as to whether you will be able to receive the COM channels from Rowridge, even with the aerial vertically orientated. This would tend to suggest that your chances of success might not be great and hence you need to use a Group A aerial for all the gain you can get.

If it proves that you can't receive the Rowridge COMs, then you need a diplexer to combine the Mendip aerial with the Rowridge one to give you Mendip's COMs and Rowridge's PSBs.

Please post a question, answer or commentIf you have Freeview reception problems before posting a question your must first do this Freeview reset procedure then see: Freeview reception has changed, Single frequency interference, and Freeview intermittent interference.

If you have no satellite signal, see Sky Digibox says 'No Signal' or 'Technical fault'

If you have other problems, please provide a full (not partial) postcode (or preferably enter it in box at the top right) and indicate where if aerial is on the roof, in the loft or elsewhere.
