experience problems, e.g. with certain MUXES disappearing. First try rescanning your
TV / set top box (do it manually if possible), but if this fails to work check on Transmitter work
or call the reception advice phone numbers. Also see basic digital fault finding.
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 ?
Its population coverage is around 500 thousand and its power is 100kW analogue.
Digital / Freeview 1.6 Kw for MUXES 1 & 2 and 1.0kW for the other 4 MUXES.
Heathfield has nineteen smaller repeaters off it to improve its signal coverage in poor areas.
Being a main transmitter it is horizontally polarised and it was a C/D group but in order to
accommodate digital it is now (technically) a wideband. That said, C/Ds often pick up
signal quite well below their designed for band, so reception may still be possible,
see Heathfield`s graph. Though this may not apply to some cheap crappy Contract
aerials. MUXES 3 to 6 are still within the original band so should be available with a C/D
group aerial, it`s MUXES 1 & 2 which may require the aerial change.
I find this somewhat bizarre because the first two MUXES are the most important
(the main BBC and ITV programmes) so one would have thought that these would be the
channels to be broadcast within the original band. For obvious reasons this scenario is
the one usually adopted.

For Heathfield we recommend the DM log for strong signal areas, the Log 40 for
medium signal areas, the DY14WB for poor signal areas, and the XB16E for those with
the most marginal signals. The dimensions and test performance of the aerials can be found on the relevant tables. If requiring a “high gain aerial” in the loft we recommend the DY14WB over the XB16 because of the former aerial`s smaller size.
All the digital output is attenuated to the South so as not to cause co-
It has been confirmed by Ofcom that when DSO occurs Heathfield will become a B
group, however those still on C/D group aerial should still get reception OK.
Our own tests prove that decent C/D group aerials (may not apply to some Contract
aerials though) work just as well as a wideband in the B group, though obviously a
B will give more gain than either.
In any event the main 3 PSB MUXES will almost certainly be receivable on a C/D.
There are two interleaved spectrum channels allocated to Heathfield, CH 54 and CH45,
which are both within the previously announced post DSO group.
For Heathfield`s channels/frequencies see its Channel Allocation Guides for before
and after DSO, these also include the frequencies for Crystal Palace, Bluebell Hill,
Tunbridge Wells, Dover, Hastings, Whitehawk Hill (Brighton), Midhurst, Guildford
and Reigate. This data can be very useful for identifying causes of co-
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.

Note the channels out of the original C/D group of the transmitter, MUXES 1 & 2 being particularly badly affected. That said, even these two MUXES would be receivable to those
in decent signal areas.
After DSO in 2012 Heathfield will officially be a B group and four of the six MUXES will
be 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 is going to be increased at DSO by a large margin. Though this may not apply to some cheap crappy Contract aerials.
