Aerial Heights

Originally as used by Radio Atlanta - 141’ (43m) high (from deck level). The top 91’ (27.7m) was welded section alloy Sparlight yachting mast. The bottom 50’ (15.2m) was what had survived of the Radio Nord mast.

The aerial was a wire cage series feed.

After the 1966 refit -

The aerial height was increased to 162’ (49m) -from deck level. The top 91’ (27.7m) was welded section alloy Sparlight yachting mast, with an added 21’ (6.4m) alloy middle section and the surviving 50’ (15.2m) of the original Radio Nord mast. (It was this mast which collapsed at sea in November 1972 - see Radio Caroline 1970’s)

The aerial was designed as a wire cage series feed, but the top 112’ (34.2m) of the mast was tuned and used instead.

The station claimed an aerial height of 168’  (51.2m).
