On the REMLR site, there is a photograph of a 30-239 in service with an aerial mount bolted on the side.
Looking at my 101, there are bolt holes that suggest it had an aerial mounted to it in the same position.
A question for those with Australian delivered 101s that served in the ADF, did your 101s have bolt holes for a sugar scoup?
A further question, does anyone have photographs of the radio setup in an Australian 101?
