Note As work takes place on various digital transmitters (to prepare for the DSO)
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).
15 miles due South of Southampton. Rowridge transmitters population coverage is around 1.75 million and its broadcasts can be picked up in many areas along the South Coast including Portsmouth, Southampton, Bournemouth, Fareham and Weymouth.
Power output is 500kW (erp) analogue and 20kW on all Digital / Freeview output.
The structure is stayed spaceframe mast with a height of 135m and a site height of 137m.
Rowridge is horizontally polarised and is an A group for the 4 analogue channels plus all
the digital. Note that MUX 2 was out of band on CH52 but it is now within the A group on CH28. Although no analogue C5 is transmitted from Rowridge it is broadcast (at 10kW) within band from Fawley, it is actually the power stations chimney ! The latter is 10 miles
to the North and so is co-
digital MUX3. Rowridge has thirty five smaller repeaters to increase its signal coverage.
For Rowridge transmitter`s TV frequencies/channels see its Channel Allocation Guides
for before and after the DSO. These also include the same information for other potentially co-
system without suffering from co-
Ofcom report that Rowridge does not transmit anything to the South, as one would expect ! DSO is due to occur in February 2012. Unsurprisingly it has been confirmed by Ofcom that Rowridge will stay as an A group at DSO.

Note the gaps in the table below for channels 31 to 35, 37, 39 to 40 and 63 to 68, they`re reserved for “other uses”....
We recommend the DM log aerial for strong signal areas, the Log 40 for medium signal areas, the Yagi18A for poor signal areas and the XB16A 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.
The channel planners were able to fit the Digital MUXES (transmitted at 20kW) within the
A group along with the analogue stations, so an aerial change may not be necessary. Furthermore those in poor reception areas, who may require an
upgrade, can take advantage of the superior performance of an A group aerial over a wideband. In fact such is the widebands inferiority at the bottom of the band that there is
no such thing as a “High Gain” wideband aerial for the A group frequencies and nobody should ever fit a “high gain” wideband on an A group transmitter, e.g Rowridge.
If the site is in a poor spot an A group aerial should be used.
On the other hand if the signal is strong (or medium) then by definition it doesn`t need
a “high gain” antenna anyway ! Under these circumstances a Log Periodic should be
fitted instead. See Rowridge Graph
It is not uncommon for many on Rowridge to suffer from co-
