FLARM antennas (SMA connector, RED marking)
Core has two separate FLARM radio transceivers FLARM A and
FLARM B.
FLARM A is used to receive and transmit and must
always be connected to an antenna
. FLARM B is only used to re-
ceive; an optional antenna may be used for better reception per-
formance.
Usage of FLARM B requires purchase of the respective feature li-
cense.
Ensure the antennas are properly and fully screwed into Core.
Nev-
er swap the FLARM and the PCAS/ADS-B antennas.
Use only
little force when inserting and tightening (1 Nm max). Ensure the
antennas are not in contact with any other object through which
there might be a regular electrostatic discharge, e.g. the canopy. In
case you use two FLARM antennas, ensure they are separated by at
least 5ft.
Ideal locations for the FLARM antenna are:
•
On the coaming of the instrument panel, in front of the compass
(4 inch, 10cm minimal distance to compass)
•
In the tail fin of the aircraft, if not metallic or carbon. Use only
extension cables available from FLARM dealers.
•
Behind the pilot’s head in the glider fuselage (not in gliders
with carbon fuselage)
The FLARM antenna must be vertically (i.e., one tip facing up, the
other one down.
PCAS/ADS-B antenna (SMA connector, BLUE marking)
Core has one PCAS/ADS-B receiver operating on 1090MHz. Ensure
you properly and fully screw the antenna stub into Core.
Never
swap the FLARM and the PCAS/ADS-B antennas
. Use only little
force when inserting and tightening (1 Nm max).
This antenna should be placed at least 1ft away from the FLARM
antenna(s). The FLARM antennas have priority over this antenna
for best placement.
GPS antenna (MCX connector)
PowerFLARM Core contains a 50 channel GPS receiver, connecting
to an external antenna. Ensure you properly and fully plug the GPS
