At 1932 feet above sea level one of the most prominent stay well clear obstacles on the Southern Great Britain half million chart.
Bearing 005 degrees and 14 nm from the Yeovilton VOR VLN 111.00 Megahertz in the Aerofly database.
I checked the height on an old half million chart, it used to be higher! The mast was 1995 feet high in the days of analog TV but the antenna cylinder was changed for digital transmissions. The Yeovilton beacon is/was? a military TACAN in real life. Aerofly should only give a DME not a VOR output as with all TACANS.
