Brief Description:    GPS Antenna Tray FWF
Benefits are no external drag, no need to run antenna wiring from aft of spar to forward of spar, no clutter sitting on top of dashboard, uses existing through-the-firewall wire routing.
Supplies: 2 DWG-14 adel clamps. 1 .063 angle 7 3/4 long. 1 mounting tray .063 4" x 7 3/4". 9 nutplates #8. 2 ea #8 flush screws,washers, metal locknuts. 8 #8 machine screws to mount GPS pucks (Garmin gave me 4, Dynon did not. Need to get some longer SS ones.). 1 #8 pan head machine screw.
Mark one hole for each antenna, drill that hole #19, drill a 5/8 center hole for wire access, mount using that one hole and then use the antenna to exactly locate the remaining holes. Everything will then fit perfectly. To drill the nutplates I just screwed a machine screw into the nut plate to tighten it to the tray and match drilled the nutplate 3/32 holes. Countersink the 3/4 angle for 2 flush screws to attach to the 2 adel clamps. If you plan ahead, 4 of the antenna puck mounting holes can use the 3/4 angle for nutplates. Crimped a TNC connector to the RG400 and cut off a 7 ft length to connect at the GTN750 with a BNC connector there. Primed, painted and mounted. Secured antenna wires to engine mount with adel clamps, then through the firewall with the rest of the wire.
