The jumper turns. One antenna loses it.
Two don't.
In belly flight (face down) the antenna points down — a clear line to the ground. The moment the jumper goes head-down (head first), their own body slides between the transmitter and the ground. A single antenna drops out — exactly at the most spectacular moment.
Head-down, Sit, Backtrack, Wingsuit — the angle changes constantly.
The patch sits flush in the side end-cap — it carries the link to the ground in belly flight. The dipole sits on top — it catches the picture when the jumper goes head-down (head first). An RF switch picks whichever antenna has the clearer view, in real time.
One U.FL output, switched — no extra power draw, no second transmit chain.
The second antenna sits flush with the shell — in the top lid and the -X end cap, screwed in, not plugged on. No bump, no snag risk. Print the transmitter with or without the antenna — same clean form.
flush · screwed in · rugged.
Up top the transmitter picks the best antenna — on the ground we receive with several at once (directional + omni, true diversity). Two safeguards against the same dropout: the picture gets through.
The demo shows the principle, computed — the real proof comes with the first jump. No overclaim.
Two antennas. A picture that never drops out.
Next, the printed proof speaks.
