Does the brick contain the transponder and ADS-b antennas or are they separate? If they are in the brick, does this dictate a need for a special location for mounting the black box? If they are separate, do they need to go outside the glider? SZ Flarm antenna and 1090 MHZ (ADS-B and PCAS) antenna would normally be mounted up above your glareshield inside the cockpit. You do not want to mount them hidden behind the panel. I expect the brick to come with antennas with short coaxial leads designed to allow this - similar to those used on current headless Flarm units like the LX Red Box and Swift made units. There are instructions available now for those units that might give you some planing guidance. There is a port for optional second Flarm antenna (not included in the package) on the PowerFLARM designed to help increase the range and that is intended for mounting externally (esp. if carbon) usually underneath the glider. If there is a transponder antenna in that area there will need to be some thougth given to mounting that antennas away from each other, and cable run lengths etc. I expect most people will install the brick and standard two antennas in a temporary setup and see how this goes and eventually add the external antenna if they want to. That's what I'm planning on doing and am in no rush to drill holes in the outside of my baby. I do expect to drill two hole in the glareshield on my ASH-26E for those two antennas to poke through. Not sure how they will fix/locate underneath yet, and the issue will be making it easy to remove and resinstall the canopy. We asked Urs from Flarm about some of this this at the PASCO safety seminar where he spoke and I think the final exact details on antennas with the brick is still being worked out. Darryl I gather new gliders now have transponder antennas in the fiberglass tail, rather than ugly sticking out the bottom, along with radio. Is it impossible to fish coax back to the tail and put some of these antennas back there without cutting holes? John Cochrane- Hide quoted text - - Show quoted text - Hi John, I installed a dipole antenna inside the tail of my Genesis and routed the coax forward to run the transponder. It needs to be kept 6" from the radio antenna and metal parts like pushrods. You may be able to mount one behind the rudder in a corner that doesn't interfere with rudder movement or cut a small hole in the bottom of the fin spar to get it out of the way of rudder. It measures 1" X 1" X 5" with a BNC coming out at 90 degrees ( I got one from Aircraft Spruce) The coax can be secured by sliding gooped-up rings down the coax from the front then allowing the rings to settle and bond in the desired locations. JJ PS..........please no cracks about the Genesis not having a tail. |
