The symbol shows the location of the Dover (Kent, England) transmitter which serves 190,000 homes. The bright green areas shown where the signal from this transmitter is strong, dark green areas are poorer signals. Those parts shown in yellow may have interference on the same frequency from other masts.

Are there any planned engineering works or unexpected transmitter faults on the Dover (Kent, England) mast?

Hello Olivier,
the link worked ok though not the you tube one. You have a decent set up there !
I live in London but get my TV from the Bluebell Hill mast. This means my aerial is looking in the same direction as Dover so I can get a snowy analogue picture from there.
I have not noticed any detioration in the signal this last month which likly means the problem you are experiencing is not caused by a digital re tune this side of the channel.
Sometimes BBC2 E56 drops out because of interference from a Belguim MUX at Brussels or Wavre. Has the picure dropped on all 4 analogue channels ?

Hello Brian,

The belgium Mux is from the TOURNAI Transmitter (3,5 Kw), not so far from Lille, for french belgium community with "La Une", "La Deux", "La Trois" and "Euronews".

Since this morning, I receive 4 new Mux digital from Dover (It's the first time for me) :
Mux with Film4 : 55
Mux with BBC : 59
Mux with Five : 60
Mux with Dave : 62
I think the power is 2 Kw

I don't know if it's new or it's because the very good weather conditions but it's stable since this morning.

You can see my video at this link in bottom of the page :

Olivier: The transmitting aerial at Dover has been replaced. It's very likely that the new aerial has been designed not to waste power broadcasting across the channel.

The planning application shows that 10 tiers of panels have been fitted to three sides of a spine with a regular pentagonal cross-section. The panels point to 36°, 324° and 252°.

While the replacement aerial is being wired up, analogue services are coming from the new reserve aerial. This is also 10 tiers of 3 panels, but the panels are attached to the north-west edge of the (triangular) mast. It's hard to read the angles off the diagram, but the panels pointing west and north-east seem to aim slightly further to the north-west than those of the main aerial.

The panels have a roughly cardioid radiation pattern, so some signal will go across the channel - but not nearly as much as before.

If anyone wants to look at the documents, go to Error and click the External Documents tab, then click View Associated Documents. In the popup window, select 'Existing Elevations'. (RG47SH)

Thanks Mike, this sounds like a plausable explanation. Strange that they should bother to re engineer the analogue aerials with just one year left.
Olivier, there was a lift to London from Dover last night + I was able to get several Mux's from there.
the current allocation is D55,D58,D60,D61,D62 and D68 (with low power D39, D42 and D45 towards Thanet). I think they are all at 2kw altough maybe one or two are less.
I noticed all the digital transmitters near you are powered up with Bovigny knocking out 80kw now. I am hoping to get French digital in London soon !

brian: At switchover, the 'analogue' aerial BECOMES the full-power 'digital' aerial. There really aren't 'analogue' and 'digital' aerials, either for transmission or reception. There are only UHF aerials, designed for different frequency ranges. The transmitting aerials are grouped just as receiving aerials are (or used to be). The smaller the range of frequencies it supports, the more efficient, so Arqiva have had antennas custom-built for each site rather than taking the off-the-shelf designs.

The low-power digital aerials just can't handle the electrical power that will be needed after switchover. At most sites they don't cover the full area that the main aerials do, either, and they're usually way down the mast to restrict how far the signals travel. They're *designed* to hit the hills to stop signals going further than they ought to.

Aerial upgrades/replacements and transmitter replacements have to be done in advance of switchover. They're not going to shin up the mast between 12am and 6am the day of the switchover! The real switchover to the new equipment happens long in advance of the announced dates - and for some viewers, causes changes in reception because the new aerial's radiation pattern is different.

I'm not sure if the new transmitters actually support both digital and analogue transmission just by flicking a switch (or a virtual switch in some software), or whether an engineer has to replace the 'exciter' unit in the rack. Probably lower-power sites are dual-standard and high-power sites have a replaceable component - I know that both are available on the market, I don't know what Arqiva have purchased.

The equipment at most main sites is approaching or exceeding 40 years old. Dover was built around 1967 with ITV on UHF starting up in December 1969. Channel 4's equipment will be nearly 30 years old, starting on launch day in November 1982. It's all reached the end of its useful life. Some sites had aerial replacements in the 1990s - these sites usually aren't getting another replacement now.

Hello Brian,

Of course you can receive Lille-Bouvigny (80 Kw) in DX-TV I think.
But I Think, it's possible for you to receive some other transmitter from our coast:
Boulogne sur Mer - Mont Lambert : 8 Kw
Abbeville : 80 and 30 Kw

I give you a link from a website friend who has made a Card of the North of France Transmitters with all channels and power:

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.
