The Supermarine Spitfire has been a favourite of aviation enthusiasts and model builders since its first appearance in 1936. In spite of all of the books magazines and websites which have appeared there is one thing which is still capable of confusing model builders; namely the various configurations of the aerial masts and aerial wires.

HF Radio

When the Spitfire I first entered service in late 1938 it was equipped with a TR 9 High Frequency (HF) radio transmitter/ receiver. This required an aerial wire and a mast. The first design of mast was a rod, about 68 cm tall; this was fitted to the initial production batch of 310 Spitfires, starting at K9787 through to L1096. A fine wire ran from the T/R equipment up the mast and emerged from the top. The other end of the wire was anchored to a small post on top of the rudder. The base of the mast was secured to a teardrop shaped insulator which appears to have been a dark brick-red colour, possibly made out of Bakelite or similar material. Many of these early Spitfires were still in squadron service during the Battle of Britain.

The second design of mast, which first appeared on N3023 was of a more complex tapered air foil shape 67.2 cm (26.45 in) tall This pattern was used for the large majority of Spitfires. A small triangular prong was fitted to the rear, serving as the anchor for the wire which now emerged from a point just behind the mast.

i am a radio ham and interested in all kinds of radio communication. i was wondering what type of radio eqt was used on the Spitfire.. i knew at some stage H.F. was used, and wondered about the VHF sets..i think WW2 , control towers seem only to have used VHF,may be, later war days…….the Film 633 Squadron was filmed at the old RAF Bovingdon , the control tower still had VHF ants mounted there (two of them). i imagine the ants would have been left, as with everything else………short wave (H.F.) radio com still used by some aircraft companies base to air, radio telephone , for use by engineers on way to a job.Any of your comments welcome ,please( i was born dec45)

I’m surprised that there doesn’t seem to have been any comment on this. The article covers the types of hf and vhf radios.

I am enormously interested in this. I design pictures of 609 Squadron Spitfires and Spitfires my grandfather flew in the Battle of Britain. Using the information found here I have been able to make my designs historically accurate. In addition to this I have used the information to discover 609 Squadron codes that were not known until now. I was able to This page has been enormously helpful to me and has broadened my knowledge of Spitfires. Thank you, cheers….
