Thanks for the reply. This is exactly what I was looking for. There are some people that are getting 6nm range on their units. That's a lot better than 1.5nm if you're trying to catch up with a buddy. The question is how do I get to that kind of range? Separately it seems I'm not alone with the PCAS range. Others are also reporting PCAS range of well under 1 mile. The product which they are delivering is not meeting a reasonable expectation of performance (particularly in PCAS) for which they and their dealers are advertising. Sub 1 mile PCAS range is basically worthless. My antenna installation is very similar to the one someone else posted and you can see a pic here... http://thezivleys.com/gliderstuff/flarmantennas.gif Discus 2b owner here. I have the brick installed with the supplied dipole antennas on the glare shield in "other than an optimal placement" and I have no issues seeing gliders out to 6nm.

Unless it has a plastic case, you compass is not helping the situation. PF wants NO metal above the plane antennas are mounted on.
