Heathfield was opened in 1969 and is located 13 miles NNW of Eastbourne. The top of the mast is 998ft (302m) from sea level and the total mast height is 145m, though the height to the bottom of the antenna shroud is 135m, see How High is High ?  

Heathfield`s population coverage is around 500 thousand and it has sixteen (including Hastings) smaller repeaters off it to improve its signal coverage in poor areas. Being a main transmitter it is horizontally polarised and it`s a B group though before switchover it was a C/D group. However, C/D group aerials often pick up signal quite well below their designed for band, reception of all the digital  may still be possible on an original "analogue group" aerial (see Heathfield`s graph ). This may not apply to some cheap crappy Contract aerials. In any event the main 3 PSB MUXES will almost certainly be receivable on a C/D group antenna.

For Heathfield 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 how after the switchover in 2012 Heathfield is now a B group (as opposed to its original C/D group). Thus four of the six MUXES are technically out of the original C/D group. But the graph shows quite clearly that the “cut off” for C/D group aerials is not precipitous and that most people in reasonable signal areas will get all the Digital OK off their “old” C/D group aerial, particularly as the power was increased at DSO by a large margin. Though this may not apply to some cheap crappy Contract aerials.

For Heathfield`s frequencies see its channel allocation guide.


Also see other relevant B group curves.


Heathfield`s TV frequencies/channels.

Note the various co-channel issues, and that`s before one brings in the continental transmitters !  Also check Heathfield`s sixteen (including Hastings) smaller repeaters .


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


How to combat co-channel interference

Just under a mile to the East is the trackbed of the ex London, Brighton and South Coast railway which was opened in 1880 from Redgate Mill down to Hailsham. Unfortunately the station at Heathfield, and line North of it, closed in 1965, the line South to Hailsham lasted until 1968. More positively the trackbed down to Hailsham is now a walking and cycling route. Two preserved railways are located near to Heathfield, The Lavender Line is 7 miles to the SW whilst The Rother Valley Line is about 10 miles to the ENE.

For Heathfield`s channels/frequencies see its channel allocation guide, this also include the frequencies for Crystal Palace, Bluebell Hill, Tunbridge Wells, Dover, Hastings, Whitehawk Hill (Brighton), Rowridge, Midhurst, Guildford and Reigate. This data can be very useful for identifying other transmitter options, see importance of "line of sight". 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.

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.

Switchover at Heathfield occurred in June 2012.

Before the switchover all Heathfield`s digital output was attenuated to the south so as not to cause co-channel interference with transmitters in that direction, including those in France !  Eastbourne, being due South of Heathfield, had particular problems with digital reception. However post DSO Heathfield will, for the first time, have an omnidirectional transmitter radiation pattern*, thus sites south of the transmitter should experience significantly improved reception.


* It will also operate as a single frequency network with Tunbridge Wells transmitter)

We are more than willing to give advice to those actually purchasing from us. Could those only seeking information please just find the answer somewhere on this site, or ring an aerial installer local to them, or call the reception advice phone numbers.

For Heathfield`s digital output see the table (above).

DSO at Heathfield occurred on the 30 May and the 13 June 2012

There are no interleaved spectrum channels allocated to Heathfield in the latest scheme, but a slight possibility exists of more TV channels being transmitted between CHs 31 and 37, but all of these can by picked up be (decent) B or E group aerials.
