Stephen, I had a transponder mode C on CEW a few years ago, it was the best piece of kit I have used. I flew the Deben beach front regularly, Dave Jackson used it for the wild coast. As a result of the King Shaka International, Ballito is mandated for all aircraft to be fitted with Transponders in the near future and as such we are (or should I say have) designed a suitable antenna ground plane. At this moment we are importing a Trigg unit for Microlight usage. The ground plane is a laser cut dish thats mounted below the fuel tank very similar to the original that I made. That was a Ally curry pot base purchased in Chakas Kraal and about 500mm in diameter. Our "dish" is clamped on to the keel and uses a u bolt assembly which originates from a yacht supplier. The intention is to design without mod approvals. We are also fitting a LED voltmeter to each trike to monitor trike battery condition. These we are making in house as well.
So any one wants a ground plane; "Designed and Manufactured by Ballito Microlight Club", we are making 29 of them !!! Not a commercial venture at all. I can also forward the dxf files for cutting and the pdf. bend details when complete if it is of help to any club with a similar problem. They will be Aquilla/Aerotrike/Raptor only fitment and no fairings.
Unfortunately the Ballito project wont be ready by the time of these March trials. After what happened to the innocent cricketers yesterday, these laws and procedures will be tightened up globally and its only a matter of time before anything that flies will have a mandatory fitment. So thats life I am afraid. In South Africa anything that gets in the way of the 2010 World Cup will be bulldozed !
Enjoy the day.
