a higher structure in 1961, the original was moved to Selkirk and is still in use.
It has the fifth highest population coverage of any TV transmitter at around 2.5 million and it is located 14 miles East of Glasgow. For the sake of impariality, that`s about 25 miles
West of Edinburgh ! The mast is 307m high, see How High is High ?
The transmitter puts out all 6 digital MUXES at 100kW (before the switchover in June 2011 it was only 20kW). Black Hill is horizontally polarised and was originally a B group for analogue, then temporarily became an E group (or wideband) whilst transmitting both analogue and digital, before reverting back to a B group at switchover. It should be noted
that wideband or E group aerials which worked before the June 2011 switchover should continue to work after that date as well.
Black Hill is a main transmitter and it has sixty four (including Torosay`s twenty two) smaller relays (or repeaters) to improve coverage in poor reception areas within its coverage area.
The frequencies given are for the analogue channels, for (most) digital MUXES add 3MHz.
* There are a few retune events (temporary MUX reallocations) just before and after DSO which may not be shown on these tables.
* Including Torosay`s twenty two.
The frequencies given are for (most) digital MUXES, for analogue channels deduct 3MHz.
I suspect that Caldbeck may well have a restricted radiation pattern in a Northerly direction and that “Caldbeck Scotland” will act as a supplementary transmitter (on different frequencies) only transmitting in this direction
Note the gaps in the table below for channels 31 to 35, 37 and 61 to 68, they`re reserved for “other uses”........
For Black Hill`s TV frequencies/channels see its Channel Allocation Guides for before
and after the (full nationwide) DSO. These also include the same information for
other potentially co-
There are two interleaved spectrum channels allocated to Black Hill, CH51 and CH48, plus 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 Black Hill we recommend the DM log for strong signal areas, the Log 40 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.

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,
please help us increase the number of people reading it.
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.

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.
DSO at Black Hill occurred between the 8 June and 22 June 2011.
Those in poor reception areas, can take advantage of the superior performance of a
B group aerial over a wideband. If you really need a “high gain” aerial (and most people don`t) a decent B group aerial should be used, see below.
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.
