Learnt about doubler plates and installed the GPS antenna – well at least test fit till after painting. Used the Dremmel to repurpose the kit supplied mounting bracket, making a nice doubler plate for the GA35 GPS antenna on top of the fuselage.
The transponder took a bit of sorting, needed to open up the floor in the centre channel to get access for the fixings. Another use for the laser level. :-). Factory said no need for a doubler plate on the transponder antenna, but I made a small one anyway.
Also learnt about UNF and UNC fixings. It’s amazing the Garmin GA35 cost so much, and I still have to source 4 specialised UNC 8-32 nuts to fit it! The bolts you do get, but they are also special 120 degrees. The Rami AV74 transponder antenna comes with nuts.
