Flarm Target direction

Ramy:
I don't profess expertise in this area, but note that in addition to the carbon underbelly there is a lot of hardware under the glare shield mounted Flarm antenna that can block downward/forward transmission: canopy hinge mechanisms, rudder pedals & adjuster, instruments, flasks, computers, and even the metal Flarm Core box itself.

Again, I not knocking Flarm - it's a useful tool. But I don't depend on it to avoid you guys . . .

I mount two long antennas on opposite sides of my canopy. Use a block with Velcro to keep the antenna tips clear of the canopy. Having transmit on both antennas as with Fusion is even better.

Unfortunately Flarm advertised dual transmit with the Core 1.1, but omitted to obtain approvals for North America.

For a new glider I'd spec Flarm and transponder antennas in the fin, perhaps with an access panel, and the secondary Flarm Antenna on a canopy side to cover the blind spot overhead the tailplane.
