you may experience reception problems, e.g. with certain MUXES disappearing.
First try rescanning your set top box and if this fails to work check on Transmitter work
or phone reception advice on 08700 100 123 (BBC) or 0844 881 4150 (ITV).
Ridge Hill TV transmitter is located 8 miles SE of Hereford and is somewhat unusual in
its location because there is no large city within 30 miles so it`s population coverage is
only about 500 thousand. Ridge Hill has seventeen smaller repeaters to improve its coverage in poor reception areas. At 100kW analogue power it is one of the smaller
main transmitters so the fact there are only half a dozen large towns within this 30 mile range makes it more unusual still. Digital is broadcast at 2kW for all the MUXES.
Where Ridge Hill is useful is as an alternative (importance of “line of sight”) to other transmitters which may be nearer. A selection of the latter, namely Mendip, Wenvoe,
The Wrekin, Sutton Coldfield, Bromsgrove, Malvern, Lark Stoke and Oxford are included
on the Ridge Hill Channel Allocation Guides (for before & after the DSO) which lists
the transmitters frequencies. Note how they all “dove tail” together.
The Channel Allocation Guide 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-
Ofcom report a small amount of attenuation on all the transmissions to the South East.
DSO is due to occur in August 2011 and it has been confirmed by Ofcom that
Ridge Hill will be returning to an A group at DSO.
Ridge Hill was originally an A group but as can be seen on the Channel Allocation Guide
it has now become a wideband for the Digital channels, though analogue Channel 5 is still within band. See Ridge Hill graph

This is my wife`s favourite picture on the entire site. As I was prone on the floor trying to get the right angle for this shot (hopefully not lying in anything too unmentionable...), a herd of bullocks became very interested and were advancing towards me in a menacing fashion. Believe me they look big and frightening when they`re towering over you so I sprang up and promptly landed in a pile of something or other (probably the other....),
all the while my good
lady was beside herself with laughter. I hope
you appreciate the resultant picture.......

Note. There are huge forces on the joint at the base of “stayed” masts. This design of structure weighs between 150 and 250 tons (depending on the size) but the tubular types,
e.g. Mendip, are about twice this weight. Then you have the additional force imparted by
the tension on the stays, in approximate terms this would double the effective “weight”.

and after (below) the DSO.
Also check Ridge Hill`s seventeen smaller repeaters
We recommend the DM log aerial for strong signal areas, the Log 40 for medium
signal areas, the XB10WB for poor signal areas and the XB16WB for those with
the most marginal signals. The dimensions and test performance of the antennas
can be found on the relevant tables. The prices of the aerials are on the Sales page.
As with all main transmitters it is horizontally polarised and it was opened for VHF
(405 line) transmissions of ITV in 1968, UHF broadcasting on the present system started
in 1972. The height of the mast is 160m (a.g.l) and it has 4 sets of stays to keep it up.
The site height is 203m and this gives wonderful views over to the East. Clearly visible to
the NE is the Herefordshire Beacon (site of the Iron Age "British Fort") which has an
altitude of 338m and if you get a chance to visit the latter I would do so as the views are stunning for almost 360 degrees. In fact the only obstructions are North Hill (397m) and its neighbour the Worcestershire Beacon which is the highest of the lot at 425m. Surely one
of the best 360 degree views in the country. Note for those not keen on walking up mountains the Herefordshire Beacon is much the easiest to ascend !
The transmitter can be seen from miles around including from the M50 which runs about
5 miles to the South. The latter was opened (from the present Junc 1, A38 turn off) in 1960 and was extended Eastwards to the M5 (Northbound) in 1962. The Southbound M5 from
this point didn`t open until 1970. The railway was what really put this area (The Malverns)
on the map and the Worcester & Hereford Railway opened in stages from 1859 to 1861, this subsequently became the West Midland and finally part of the Great Western.
The Ex Hereford to Ross line passes to the West and was opened from 1855 to 1964 and
to the East the line from Ledbury to Gloucester opened in 1885, closed as far as Dymock
in 1959 and the remaining stub to Gloucester in 1964.
