Forfar Band 1 and Band 2 HP

Photographs taken in 1985


The HP band 2 antenna is visible, possibly the Band 1 transmitting system had been removed by then.


However the Band 1 receiving systems were still there. When these stations were built it was usual to have the receiving systems on a separate tower in order to get the required isolation between antennas.


The loops at the top of the tower are there to reduce the effect of precipitation interference, that is, noise on the picture caused by electrically charged raindrops.

More information on the suppression of corona and precipitation-interference can be found on the links to the BBC R&D website below.
