TNC connector (not BNC) ready for coax cable.
Used acetone to remove primer for better grounding Prior removal primer for doubler grounding When Wing mounted to Fuse, will route OAT wire via these 3ĭoubler prepped. Single rivet w/ epoxy located/mounted Snap Bushing supports.
RV14A QUICKBUILD SKIN
Prior to mounting doubler removed primer on inside Fuse skin for best ground contact (Garmin instructions for G3X/GA 35 antenna). Reason I checked with Vans was Garmin installation recommends doubler w/ 12 - 16 rivets. Eric Rushing at Vans Prod Support confirmed their demo RV14's and RV10 did NOT use a doubler (but mounted close to stringer). Fabricated alum doubler referencing couple other RV14a builder logs about 1" larger than antenna. Positioned Garmin GA 35 GPS WAAS Antenna on top Fuselage behind rear window. OAT wiring in Wing, GA 35 GPS antenna ( 3 hrs )įabricated 3 alum "brackets" to hold SB437-4's to guide/support OAT wire in LH Wing (from Wing root to 1st Access panel) - for when Wing assembled to Fuse. Routing/securing with static line next stepĪdded snap bushing to vertical support, & re-routed air lines TNC (thread on stype) crimped for GPS antenna So I revised to route coax and these 3 lines together as shown below vs original pass over the vertical support.Ĭoax cable prepped, then center pin crimped on As I routed coax cable nearby, I discovered perfect spot for a SB750-10 (not referenced in Vans instructions). Also re-routed Static, Pitot and AOA air lines at IP. Why Garmin uses this expensive connector at this antenna stumps me. Crimped on TNC (threaded style - and expensive at $23 vs $3.25 for BNC) at antenna end.
Then routed RG400 Coax cable from aft of baggage area through center tunnel up to IP for GPS WAAS antenna.
RV14A QUICKBUILD HOW TO
(Good videos from Stein Air and HomebuiltHelp , and EAA show how to do this successfully. Very difficult to pass cable through SB at transition to center tunnel.but eventually worked. Routed RG400 coax from RH side Fuse at Comm whip antenna through to center tunnel. Progress bundling LH Common Harness, other wires & air lines
Red wire is Fuel Pump power, which under top cables is joined toĭiscrete #3 #2 wire (purple/green stripes) Yellow denotes adel clamp (nutplate had to be installed via blind rivets at this Installed nutplates so I could use -12 size cushion clamp ( seems nutplates should have been done via Quickbuild, since not otherwise denoted to do earlier) Bundled & protected LH Common Harness + GPS cable + Static/AOA/Pitot air lines + Discrete #3 #2 inside center tunnel and up to back of IP. Will provide notice on display "Fuel Pump ON". And Pin 42 = Discrete #3 for Purple/Blu wire.Ĭrimped connection Discrete #3 (now Discrete #2) wire to Fuel Pump Power wire adjacent to pump in center tunnel. This aligns Purple/Grn to Pin 41 and Discrete #2.
So I switched Purple/Grn wire and Purple/Blu wire in connector J244 at GEA24. #3 is locked in by Vans program for Canopy Warning uploaded into G3X.
RV14A QUICKBUILD UPDATE
Update 5/29/19: needed to switch Fuel Pump On to Discrete #2, so Discrete #3 could be aligned with Canopy Warning. Discrete #3 (now Discrete #2) connected to Fuel Pump, etc ( 3 hrs )
