PowerFlarm Core + Libelle 301

That's what I was getting at. Wondering if it is worthwhile.

Try it with one (FLARM A) and run it through the RF Range Analyzer. If you have relatively circular coverage and adequate range, you may elect not to install FLARM B (if you are not grandfathered, this is also at extra cost).. If you don't have good circular coverage, you can experiment with FLARM B..

I have an SZD-55 and it gives me a roughly circular 5.5 km, which is good for me. A friend, also with an original CORE, has the same type glider, and had to install FLARM B to get a good all-around view. Antenna placement is fairly critical (distance between antennae, and GPS antennae). 'Verticality' of FLARM and ADS-B is important - set it so it is vertical in flight. This is due to the dipole antenna beamform.

The second antenna gives you a look at parts of the sky the other may not see.

You can do some of this on the ground. Install your system, and then drive around it with a FLARM Portable in your car (airfields have a lot of space to do this kind of thing). Run the range analyzer, or have a buddy drive it around while you observe in the cockpit ranges.

I've installed FLARMs in club ASW-20, ASW-24, Puchacz, own SZD-55, Junior. All work with only FLARM A (but none have carbon fibre and are transparent to RF (except for metal instruments); I run the RF Analyzer whenever an instrument change is made, and a couple of times a year to ensure the 'smiling piece of meat' (me) is protected.
