I built mine that way using a doubler on the inside of the skin and picking up the rivets on the stringer to strengthen the doubler. I had to put a joggle in the doubler to do it, but there are other ways to pickup those rivets too. Just have to get a bit creative.

I have a top mount and bottom mount. Here is a photo of the doubler I constructed spanning the two stringers. What is missing in this photo is the tapered wedge that goes between the skin and the doubler. The antenna mounting bolts go through the skin, the tapered wedge, and the doubler. The skin is not flat at this point and if you attach a doubler directly to the skin it will flatten the curved area of the skin. -------- Bill WA0SYV Aviation Partners, LLC Read this topic online here: http://forums.matronics.com/viewtopic.php?p=443558#443558 Attachments: http://forums.matronics.com//files/img_1263_169.jpg ________________________________ Message 3 _____________________________________ Time: 06:28:19 AM PST US Subject: Re: RV10-List: Re: Comm antenna on top From: John Trollinger I have both my antennas on the belly of my 10 and have never had a problem reaching anyone on the ground.

Most have no issues at all with a pair of bent whips on the bottom, however most is not all. It is usually also pointed in somewhere in the recurring thread that in those rare instances where there's an issue you can just use a cell phone. That said, I have personally experienced the issue and one of the things I'm doing different on this plane (2nd RV-10) is putting one on top and one on bottom. To each their own.

Nash" Subject: Re: RV10-List: Tech in the front office - Part quattro An additional note on the android side of things: With the exception of the brief month where FlightPro was under legal dispute, I've been very happy with my Nexus 9, Flight Pro, and an XGPS-170 ADS-B receiver. The combination is probably half the price an iPad + ForeFlight + Stratus. I've used the foreflight/stratus combination and was perfectly happy with it, but I don't want to buy hardware/software that's exclusive to each other. I'd rate android/flightpro/xgps170 as about 90% as good as the foreflight solution. Foreflight is better at some things, but there are perfectly good android alternatives. I think Avare is usable, but nowhere near as polished as the other $$ Android apps. I'm glad it exists for free, and I keep it around as a backup. For what it's worth, I'm using it in a Cessna 182 with 1966 avionics while I build the RV-10, so I can't comment on how well it integrates with a modern EFIS.
