I've just bought (from Oxfam!) a copy of a BBC TV 25th anniversary
publication from 1961. Absolutely fascinating - it gives a good
technical history from pre-war years to early 625 line and colour test
transmissions.

But what impressed me the most was the coverage areas of those early
VHF transmitters - especially Holme Moss. It covered almost the whole
of northern England (coast-to-coast) and even north Wales (including
Anglesey).

Now I appreciate that the range of a VHF ground wave is proportional
to the wavelength, and that the wavelength here is about twice that of
present-day FM, but all early VHF (valve/transistor) FM radios I have
used have been hopelessly insensitive by modern standards and I find
it amazing that a VHF TV transmitter could have covered an area with a
100 mile radius!

So, does anyone know how easy/hard it would have been to receive Holme
Moss in Lancaster or Liverpool or Lincoln around 1960? Did they have
to put up 10 element aerials with pre-amps?


Here in West Yorkshire prior to the start of the Holme Moss transmitter
reception was from Sutton Coldfield.

No multi element aerials were not used for the BBC on band 1, H and X
aerials were used.
( multi elements came in with Independant TV on band 3, from Emley Moor
and Winter Hill)

See my post about a three element near me,
and look at this nice four element with delta-match on Bill's site
