In
1951 I was a director and service manager of a radio and television
retailer having shops in Rhyl and Holywell. The Holm Moss television
station had just opened and as we were in the service area of the station
we were very busy installing aerials and supplying television sets.
We
were asked by a local customer (Mr Loasby) who was moving to live
in Rhiw if we would install a TV aerial for him at his cottage. Rhiw was
over 120 miles from Holme Moss and well out of the service area, so we
declined as we felt that the received picture, if any, would be very poor
and as it was a cottage the aerial could not be very high. However, he was
insistent we should try and offered to provide a 60 foot mast on which we
could install the aerial and he agreed to pay all expenses whether or not
it was successful.
Very
early one Sunday morning in the summer of 1952 I set off with his Philips
1800A TV (pictured left) set in the van and, strapped to the roof
rack, a huge top-of-the range eight-element aerial and aluminium pole.
I
arrived on site to find that he had made some private arrangement with
several local GPO linesmen who were standing by with ropes and tackle. A
wooden 60 foot ship’s mast was already there. So was a stout 20 foot
wooden telephone pole installed in the ground. At the top of the pole was
a pulley block with ropes to a matching pulley block 20 feet up the mast.
The intention was to raise the mast by pulling on the rope until the mast
was vertical and then a GPO gentleman on top of a ladder would secure the
mast to the pole whilst guy ropes were installed.
The
top end of the mast was resting across a garden wall ready for the
installation of the aerial. The GPO gentlemen had fixed clamps to hold the
metal aerial pole to the mast, so all I had to do was to carefully
assemble the aerial, connect the cable and fix it to the mast so that it
would be pointing toward Holme Moss when the mast was erected.
All
this activity on a Sunday morning aroused the interest of most people in
the village and some from the surrounding area, it seemed. Quite a number
were standing in front of the nearby chapel ignoring the requests of the
Minister to attend the Sunday service.
Photographs show the aerial and mast being erected at Y Ffôr.
The
raising of the mast started with the GPO gentlemen confident that all the
preparations had been made correctly. However, their experience had always
been with bare wood telephone poles, not a shiny, slippery, smooth,
varnished mast. All went well until the mast reached an angle of about 35
degrees when the lashing holding the pulley block to the mast slipped down
the mast and the mast together with the aerial crashed down on to the
wall. The sudden shock caused all the 9 foot element rods to shear off and
spin into the air like javelins. Fortunately no one was hurt, just a few
red faces belonging to the GPO gentlemen and a slightly deeper hole in our
customer’s pocket.
It
was probably the most exciting event Rhiw had seen for some time. The
Minister made capital of the disaster by saying that it was an ‘Act of
God’ as punishment for working on the Sabbath.

Coverage
It is the aim of the BBC to provide a
television service covering, as far as possible, all parts of
the United Kingdom. This entails the provision of an adequate
number of transmitting stations of sufficient power and the
means of conveying the television signals to them. It is also
important that receivers and aerials should be suitably
designed and chosen to suit local conditions; the BBC is in
constant touch with the radio industry and the trade on these
points. Already some 98 per cent of the population are within
range of the service and this figure will be raised to about
98.2 per cent when additional stations already announced and
under construction are completed. To extend the service to the
remaining 2 per cent or so presents a very serious economic
problem because these people are distributed over a large
area.

A
few Sundays later I travelled to Rhiw again with a new aerial to replace
the damaged one. This time the mast and aerial were erected successfully,
(God must have looked the other way) I put a plug on the aerial cable and
connected the TV set and up came the picture, black and white of course,
somewhat grainy, but viewable. At that distance from the TV station
reception would always be affected by the weather, poor during the summer
months, with frosty winter nights providing the best pictures.
