 Totley Rise Transmitter                                  OS Grid Ref SK 322 807
Totley Rise television transmitter is a relatively low power relay off Emley Moor (via Crosspool) which is "aimed" into the River Sheaf / Old Hay Brook valley. It is necessary because some of this area is shielded from Emley, Crosspool and Belmont by the hills
(see ATV topography map). The TX is a Vertically polarised B group and it`s output is 12W.
Only the four basic analogue programme channels are transmitted, i.e. no C5 or Digital though this is due to change when the DSO occurs in September 2011. Note that only the three basic PSB MUXES will be transmitted from Totley, not all six of them.
 As one can see from "Transmitter Channel Allocations", BBC1, BBC2 and C4 from Totley clash with three of the digital MUX`s off Crosspool and for this reason the latter only broadcasts Digital TV at reduced power in this direction. Further study of the TCA reveals just how difficult it is for the "Channel Planners" to add in the additional digital channels,
for example ITV clashes with MUX6 off Emley and MUX1 off Waltham. In addition Totley`s BBC2 is also transmitted on the same frequency as MUX5 from Waltham ! This would not normally be a problem because Totley is a low power directional relay on the one hand,
and on the other it`s "catchment area" is shielded from Walthams television output
by the hills. Those who live in areas which can pick up both transmitters may have to be careful where they site their aerial in order to try and “shield” it from the unwanted transmissions.  
 Totley mast can be difficult to see as it is hidden behind the trees of Poynton Wood, but it
is actually situated just off Poynton Wood Glade. It looks just like a telegraph pole and is often mistaken for one !

Totley transmitter`s Log Periodic array.

 

The bottom (vertically polarised) one receives the signal from Sheffield / Crosspool, which in turn

gets its signal from Emley Moor, thus it is a

repeater off a repeater !

The top array (also vertically polarised) retransmit into the valley.

 

Note the broadcast authorities use of

Log Periodics, an aerial we recommend

to use wherever possible.
