I cut out the antenna mount per the template I made, and then measured with an adel clamp how far from the edges I would need the clamp holes. I’m using a different antenna than most of the Safaris use because the one they spec on the helicopter is actually an antenna designed for the bottom of the aircraft, and it’s bent to allow for the close proximity to the ground. Safari uses it to allow for clearance of the main rotor blades, but in actuality, the proper antenna has plenty of clearance. If you bend the main rotor blade down as far as it can go, there is over 32” of clearance for an antenna. The antenna I’m installing is only 22” tall, and therefore has plenty of room.
I took an EAA electrical class back in Oshkosh WI, and the instructor who was teaching it had over 50 years of working with and designing radio communication antennas. The difference between the two styles in both range and clarity was astounding. He recommended I install a standard “top of the aircraft” antenna if possible.
The antenna I bought after getting a credit back from Safari for the original came with a great template for installing the antenna base. I measured equally from all sides of the triangle and kept it parallel to the centerline of the boom. I drilled the holes for the mounting screws and also for the antenna. Once I deburred all the edges and holes, I placed it in the pile headed for the painter.
