Show historic services

Westerglen is located in Stirlingshire, a few miles south-west of Falkirk. It is one of three stations to transmit BBC Radio 4 on 198kHz Long wave and also transmits BBC Radio Scotland, Absolute Radio and TalkSPORT on Medium Wave. It is one of the UK's earliest broadcast sites, entering public service way back on 12-Jun-1932.

There are four structures at the Westerglen site. These are the two 152m (500 ft) stayed
lattice masts. The mast on the left (east), transmits the long wave service. The other mast
transmits all of the medium wave programmes.

The MF mast.

The LF mast.

The third lattice mast is 64m high and can be used as a reserve aerial for the MF services.

The fourth structure at Westerglen is this tower. It is not used for transmitting any of the broadcast services.

This last photo, below, taken by Peter Bigwood, shows the top of the Long Wave mast at Westerglen. Its a Marconi umbrella, where the topmost guys are connected electrically to the top of the mast, and form a downward sloping 'top hat'. This effectively increases the electrical length and so raising the radiation resistance, which draws more RF current into the radiator so it radiates more efficiently.

Station History and key dates:

Westerglen was the third instalment of the BBC regional scheme. It replaced the original BBC stations at Glasgow (5SC), Edinburgh (2EH) and Dundee (2DE). Two 152m (500 ft) stayed, lattice masts were erected to support a T-aerial for the regional transmitter between them; an 'umbrella' aerial for the national transmitter was erected around one of the masts.

A T-aerial was initially used to transmit long wave. The new LF aerial arrangement was an umbrella configuration using nine wires each 180m long with an insulator half way down. The lower section was made up with parafil rope.
