Aerials

Sept 1972-May 1973 – original Radio Atlanta/Radio Caroline South aerial mast - 120’ (37m)

May 1973 engineers and DJs on the Mi Amigo erected most of a new 165' (50m) lattice mast.

A ‘sausage’ aerial strung between the Mi Amigo’s masts was used when two frequencies were being broadcast from the ship.

Early July 1973 remaining sections of the lattice mast were put in place giving the structure a total height of 180' (54.8m) (this collapsed on  1st October 1973, and was replaced by a temporary aerial system, but this failed on 18th October 1973)

24th December 1973 the final section of a  new 165’ (50m) mast was completed, (this was the mast which remained visible for 6 years after the Mi Amigo sank in March 1980)
