Sea King HAR3/3A HF aerial layout

[Rickoshea52]

I had a look through my Sea King course notes and found these two illustrations of the HF aerial lay out for the HAR3 and 3A as the Airfix instructions are incorrect and appear to be a hybrid of both types. 
I hope Britmodellers find them useful.

With a 3A still to do, filed away - thanks!

One point to note is that the 3A drawing shows the final 'short' VHF(FM) 'whip' aerial under the tailboom - the original version was longer, as seen here:

Later replaced by the shorter version:

That originally retro-fitted to the 3 appears to have been the longest, as in the pic here (airliners.net image so link, rather than pic itself):

Hmm I believe that was the V(mar) aerial ...not much point having Vtac...whilst still got upper and lower V Air blade antennas.

I am sure that you realise that the Mk3 and 3a had different HF radio set ups

That’s the reason I posted the extract from my notes, it’s the main observable difference between the two marks and catches modellers out who follow the Airfix instructions.
