Bluebell Hill is 3 miles North of Maidstone and was opened in 1974. Its power is 30kW
on analogue and 2 to 3kW on Digital / Freeview. The transmitter has (only) three
smaller repeaters to improve coverage in poor reception areas within its coverage area.
Ofcom quote Bluebell Hill`s maximum population coverage as being about 1.5 million,
but that includes households which may well be on another transmitter with overlapping
coverage.
Originally Bluebell Hill was an EH group. Only the 4 analogue stations plus MUXES 1, 4, 5 & 6 are available within the E band, see Channel Allocation Guide. A wideband may
possibly be required for MUXES 2 & 3 (on channels 24 & 27), see Bluebell Hill`s Graph
That said, I`d have thought that most E groups would work fine, unless you`re in a very
poor signal area. No analogue Channel 5 is transmitted.

For Bluebell Hill we recommend the DM log for strong signal areas, the Log 40 for
medium signal areas, the DY14WB for poor signal areas, and the XB22WB 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 XB22 because of the former aerial`s smaller size.

Also check Bluebell Hill`s three smaller repeaters.
The frequencies given are for (most) digital MUXES, for analogue channels deduct 3MHz.
* There are a few retune events (temporary MUX reallocations) just before and after DSO which may not be shown on these tables.

Note that MUXES 2 and 3 are out of the original E group of the transmitter. But the graph shows quite clearly that the “cut off” for E group aerials is not precipitous and that most people in decent signal areas may well get all the Digital OK off their “old” E group aerial.
At DSO in Jul 2012 Bluebell Hill will become a B group, although all E group and wideband aerials working before switchover will continue to work afterwards. For Bluebell Hill`s frequencies see its Channel Allocation Guides for before and after the DSO.

Question. Why is Bluebell Hill so called ? I couldn`t possibly guess, how about you ?
Just like Sandy Heath ?
Now then, not so fast young man.
George Wise contacted us to say that Bluebell Hill isn`t Bluebell Hill at all, it`s actually Blue Bell Hill. Furthermore the moniker has nothing to do with flowers,
it refers to a Blue Bell which used to summon the horses to draw the vehicles up
the hill between Maidstone and Chatham.
Consultation of a map of the area proves George to be right.
However the transmitter is called Bluebell Hill by the BBC so I must (somewhat regretfully....) stick with the “incorrect” name.
Incidentally the BBC has got a few of the other transmitter names wrong as well, though, as usual, I can`t actually remember which ones they are at the moment !
The nearest railway to Bluebell Hill is, very unusually, one which only opened in 2003, namely the Channel Tunnel Rail Link. In fact the line actually goes under Bluebell Hill in a tunnel which is only about half a mile to the SW of the transmitter.

Some post switchover MUX allocations (particularly CHs 61/62 and 49/50) may well be changed due to the 800MHz clearance.
If you`ve found this site informative and, hopefully, interesting as well,
It was revealed by Ofcom (on the 13 June and the 27 June 2012) that Bluebell Hill will become a B group at DSO, in 2012, although all E group and wideband aerials which were working before switchover will continue to work afterwards.
Those still receiving poor digital after switchover will have the use of a B group as an option. Technically CH54 is above the B group, but all B group aerials work fine at this frequency.
At switchover Bluebell Hill`s digital power output will increase from the pre DSO level of 2 to 3kW output up to the post DSO level of 20kW.
There is one interleaved spectrum channel allocated to Bluebell Hill, CH56, plus there is a possibility of 2 or 3 more MUXES being transmitted between CHs 31 and 37. All of these can be picked up by (decent) B group aerials.
For Bluebell Hill`s frequencies see its Channel Allocations Guides for before and after the DSO. These also include the same data for some of the other major transmitters also receivable within Bluebell Hill`s coverage area, namely Crystal Palace, Sandy, Sudbury, Dover, Hastings, Heathfield, Tunbridge Wells, Whitehawk Hill (Brighton), Midhurst and Reigate. The Channel Allocation Guides can be very useful in the diagnosis of

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 Bluebell Hill is due on the 13 June and the 27 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.
