Just bought a new Hyperion double rhombic today, some questions I wanna ask to. I'm using P3S now. Have been doing some tests. In a wide open area, the furthest range I ever got in stock only 300m (984ft) and 120m (393) alt. After that, RTH kicked down. 1. Is this tx or rx antenna? 2. Should I install the rx (if it tx) also onto my bird? 3. Would it make double range distances to my bird? 4. Has anyone here ever tried and used it? What about the result? Thank you.
