The one behind the baggage bulkhead is off-center a bit if that's important. I'm getting ready to mount the NavWorx UAT and GPS antennas on my Navion and both will need to be off the centerline due to skin lap joints. If you don't have an autopilot pitch servo already make sure you leave mount it far enough aft to leave room for one near the bellcrank. You could also put it under the baggage pushrod cover. You'd probably need to offset it for the cable to clear the pushrod. I don't remember if the flanges go inboard or outboard so you might need the doubler unless the other baggage floor panels are removable. That's a shorter cable run and one less bulkhead to penetrate.

Hmmm... ADS-B is telling others where you are. ADS-B OUT and ADS-B IN are supposed to be transmitted and read by aircraft for collision avoidance.. I once had the job of converting electronics in a couple of army Cessna 337's - the front and rear engined beast. There were being returned from Vietnam and turned over to the FBI for use at home. The equipment in them was military including things like TACAN and, of course they used transponders in mode B, the secret identification friend or foe. All of the interesting stuff had been removed. But installing the new transponder was a problem. I couldn't find the L-band antenna that I knew was there. A friend found a funny antenna on top of the cabin which turned out to be what I was looking for. Why on top ?? Well, thinking about it the 337's were low flying beasts that were spotting for the F4's and B52's above and that's what the transponders were for. Now we have ADS-B and not only the ground based radar sets will be looking. It will likely become common for ADS-B IN, in larger, faster, and higher flying airplanes, to depend on reading your ADS-OUT information in a way that can be independent of ground facilities. How long will it be before the instructions get changed about antenna locations? Will we need two of them? ------------------------------------------------------------------------------------- Other Matronics Email List Services ------------------------------------------------------------------------------------- Post A New Message avionics-list@matronics.com UN/SUBSCRIBE http://www.matronics.com/subscription List FAQ http://www.matronics.com/FAQ/Avionics-List.htm Web Forum Interface To Lists http://forums.matronics.com Matronics List Wiki http://wiki.matronics.com Full Archive Search Engine http://www.matronics.com/search 7-Day List Browse http://www.matronics.com/browse/avionics-list Browse Digests http://www.matronics.com/digest/avionics-list Browse Other Lists http://www.matronics.com/browse Live Online Chat! http://www.matronics.com/chat Archive Downloading http://www.matronics.com/archives Photo Share http://www.matronics.com/photoshare Other Email Lists http://www.matronics.com/emaillists Contributions http://www.matronics.com/contribution ------------------------------------------------------------------------------------- These Email List Services are sponsored solely by Matronics and through the generous Contributions of its members.
