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.

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.

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

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.

DSO at Heathfield occurs on the 30 May and the 13 June 2012.
MUX4 will temporarily operate on CH48 at 2kW for a short period after this.
Heathfield will become a B group at DSO, however those still on C/D group aerials should still get reception OK. Our own tests prove that decent C/D group aerials work just as well as a wideband in the B group, though obviously a B will give more gain than either. This may not apply to some Contract aerials though.
In any event the main 3 PSB MUXES will almost certainly be receivable on a C/D.
At switchover Heathfield`s digital power output will increase from the pre DSO 1kW to 1.6kW output up to the post DSO level of 20 kW.
There are two interleaved spectrum channels allocated to Heathfield, CH 54 and CH45,
which are both within the previously announced post DSO group. In addition there is a possibility of 2 or 3 more MUXES being transmitted between CHs 31 and 37, but all of these can by picked up be (decent) B or E group aerials.
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 other transmitter options,
see importance of "line of sight". The Channel Allocation Guides can also be very
useful in the diagnosis of co-

Note, as work takes place on various digital transmitters (to prepare for the DSO) you may
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.
Digital switchover at Heathfield is due on the 30 May and the 13 June 2012.
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.
