Flarm range

Hi Ramy, since I upgraded to 6.02, I've seen a range increase from 5.4 km average to 6.4 km average (over about 23 hrs flying so far this season), and also an increase in max range. I use a Core and centre-fed dipole FLARM antenna. Each of these were in the vicinity of 1,100 flarm events on single flights. I would check my antenna - particularly if you shortened it - with a known good antenna (connector tightness, etc). I crewed at the Chilhowee contest, and the consensus there was that the ranges had increased, and thermalling false alarm rate had dropped.

Dan, I'm getting ready to shorten my PF antennas (as part of a cockpit wiring "clean-up" effort), so I'm curious about your comment above. Are you suggesting that shortening the antenna wires can cause range issues, or is it a matter of making sure the shortening is done properly?

I'm planning on doing it at the antenna end (as described by 3U on his web site).
