Note the repainting in progress (it certainly seems to need it !) and the “Bosun`s Chair”
being used to ascend the mast, see below.

Incidentally if you are ever in this area of the beautiful North Yorks Moors National Park it`s worth visiting Rievaulx Terrace and the Abbey below it. (Picture Justin Smith ATV)

On the right is the winch (and it`s anchors ! ) to hoist the “chair” up as required.

Also check Bilsdale`s fifteen smaller relays.
Bilsdale`s Post DSO Channel Allocations (below), apart from its other uses this guide shows clearly that Bilsdale will remain a K group (for three of the six MUXES) after DSO.
Although MUX6 (on CH50) is not technically in the K group our tests reveal it to work at
least as well as a wideband at this frequency.
Note the gaps in the table below for channels 31 to 35, 37, 39 to 40 and 63 to 68, they`re reserved for “other uses”....
Bilsdale`s channels in relation to the UHF TV band and the gain curves of the aerials
we recommend for it. DM Log Log40 Yagi18K XB16K
Note the channels out of the original A group of the transmitter, and there are more of them after DSO ! (see Channel Allocation Guides below)

In fact because of Wideband antennas poor response at the bottom of the band nobody should ever fit a “high gain” wideband on any K group transmitter, e.g. Bilsdale.
If the site is in a poor spot a K group aerial should be used. 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.

We recommend the DM log aerial for strong signal areas, the Log 40 for medium
signal areas, the Yagi18K for poor signal areas and the XB16K for those with the most marginal signals. The dimensions and test performance of the antennas can be found
on the relevant tables. The prices of the aerials are on the Sales page.
The predicted date for Bilsdale to switch over is September 2012.
It`s a bit of a shock but it has been confirmed by Ofcom that Bilsdale will NOT be returning to an A at DSO. If one requires all the Digital channels one will need a
K group (or wideband). However the main MUXES 1 to 3 (the PSBs) will still be receivable on an A group.
For Bilsdale`s frequencies see its Channel Allocations Guides at the foot of the page for before and after DSO. These also include the same information for Pontop Pike, Chatton, Fenham, Emley Moor, Wharfdale, Idle, Keighley, Sheffield, Belmont and Olivers Mount.
All these transmitters are receivable within Bilsdale`s coverage area and this information
can be very useful for identifying causes of co-
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-
Bilsdale`s radiation pattern (as reported by Ofcom) reflects these co-
