Moel-Y-Parc television transmitter is located 15 miles WNW of Chester and was opened in 1963. It is a cable stayed structure around 240m in total height, see How High is High ?

Moel has a population coverage of about 300 thousand, though I can`t help wondering if the latter figure varies according to whether it`s the holiday season ! It must be pointed out that quite a high proportion of those within Moel`s coverage area choose to watch the programmes broadcast from English transmitters (e.g. Winter Hill) which is easily spotted by which way the aerials(s) face. Whether this is due to a lower Welsh content is a question I would prefer to leave to the reader to answer but I do wonder if this was also accounted for when the coverage figure was arrived at ?

The structure is built near the top of a mountain (the actual site height is 340m) and anyone visiting it will be rewarded with fabulous views, particularly if you walk up to the Trig point just behind it.


As a main transmitter Moel Y Parc is horizontally polarised and is a B group, it also has twenty smaller repeaters to improve its signal coverage.


Power is 20kW for MUXES 1 to 3 and 10kW for MUXES 4 to 6.

(Pre DSO the transmission power was 1kW for MUXES 1 to 4, and 250W for MUXES 5 & 6)


DSO occurred in November 2009.


HDTV has been transmitted since June 2010 on MUX3.


There is one interleaved spectrum channel allocated to Moel, CH 56, which is more or less within the B group. This is for a possible local TV channel for Mold. It must be admitted that at CH56 a B group may be a little down in gain on some widebands, but it should still be working reasonably well up there. This may not apply to some cheap crappy B group Contract aerials

In addition, there are two new lower power HD MUXES planned for transmission (in the CH 31 to 37 gap) on CHs 32 (at 10kW) and 34. Both of these channels can be picked up by decent B group aerials.

Some post switchover MUX allocations (particularly CHs 61/62 and 49/50) may well be changed due to the 800MHz clearance.                     


The frequencies given are for (most) digital MUXES, for analogue channels deduct 3MHz.


Note Storeton Wales which started transmitting after DSO in October 2009. This will rebroadcast Welsh Language MUXES (from Moel Y Parc) in a 30 degree arc around Flint.

Also see other relevant B group curves.

Moel Y Parc`s frequency/channel guides also provide the same information for Llanddona, Winter Hill, Storeton, Fenton, Sutton Coldfield, The Wrekin and Conway. This data can be very useful for identifying possible alternative transmitters. The Channel Allocation Guides can also be very useful in the diagnosis of co-channel interference problems and can also be invaluable if you are trying to find a spare channel for a modulated output (e.g. for a Sky box or CCTV system) to be added to your TV setup/distribution system without suffering from co-channel.


Moel Y Parc can can be seen from the main railway line along the N Wales coast which was originally opened (by the Chester & Holyhead railway) as far as Bangor in 1848. Two years later Stephenson`s famous Tubular bridge was opened across the Menai straights and the line finally reached Holyhead. This line to North Wales was once so busy (particularly in the summer with holiday makers) that it was four track for the 34 miles from Chester to all the way to Abergele. These days most people go by car along the A55 "Express way" which has undoubtedly improved access to this area of Wales but at what cost ? The road is already full to bursting half the time, I can`t help wondering where all the cars went before it was there. At least they went to the trouble of building a tunnel under Conway (opened around 1992) because constructing a huge dual carriageway through that beautiful area would undoubtedly have been a crime.....

For Moel Y Parc we recommend the DM log for strong signal areas, the Log36 for medium signal areas, the Yagi18B for outdoor installs in poor signal areas, the XB10B for loft installations in poor signal areas, and the XB16B for those with the most marginal signals. Unless you have a massive loft we`d normally recommend an XB10B for loft installs (over an XB16) due to smaller size of the former aerial.  The dimensions and test performance of the aerials can be

found on the relevant tables.

Note, due to the new phenomenon of MUXICAL chairs you may experience problems with certain MUXES disappearing. First try rescanning your TV / set top box, do it manually if possible.

If this fails to sort it check on transmitter work or call the reception advice phone numbers.
