The original aerial - installed when the ship was fitted out in Guernsey - was 161' (49m) high (from deck level).
The top 100’ (30.5m) was a welded-section alloy Sparlight yachting mast and the bottom 61’ (18.6m) was an alloy test mast from the racing yacht Norsaga. The top 100’ (30.5m) collapsed at sea in April 1966.
The replacement (installed in Grimsby) was 151’ (46m) high (from deck level). The top 90’ (27.4m) was a welded-section alloy Sparlight yachting mast, mounted on the originally installed alloy mast from the racing yacht Norsaga.
The station claimed an aerial height of 154’ (46.9m) - measured from sea level.
The aerial was of the vertical wire cage series feed type
