Default DP antennas

+1 for Delta Pop Antenna, Mr Don is a very kind guy ; I have five delta pop antennas on my -7 (in short final of build) 2 bent comm for belly, 1 ultra low drag for Dynon txp and 2 other for Power Flarm anti collision system, one of those is built for specific 868 MHz request for that device.
All antennas works great already from the shop

ciao

Default Since we're on antenna locations...

I noticed Jesse Saint recommended putting the transponder in the tunnel just aft of the firewall (on another recent post). Based on other's reports, I'm thinking it may get a bit too warm there for the electronics to be happy. Does anyone else have experience with this location (which would certainly be convenient in my case)?

Transponder antenna, not transponder.

But it's so pretty that it has to be worth 10 knots...and Don helps support the Beer Fairy too!

I just mounted my transponder, ADSB receiver and ELT behind the baggage bulkhead. I have seen other websites with these mounted in this location. I have not heard of any issues with heat buildup. These unit pull .6 amps total. With this large area I cannot see heat being an issue.

Anyone with real world experience either way?

Hmmm.... I have a 3d printer and a Solidworks license. Anyone have a suggestion on what airfoil to try? Would be simple to house the ball on a stick inside.

I can print in ABS, PLA, polycarbonate.... Others too

I'm a little confused on something that I know you guys will know the answer to. If I go with the garmin GTX 23 ES, I only will need one antenna to satisfy XPNDR/ADSB in/out requirements, correct? It seems like many people are planning on two antennas. Am I missing something?

Hey Andrew, I just went through this same question process myself, so I'll try and answer here. Basically, the GTX23ES is an "ADSB Out" transponder (no "in"), and connects to its own transponder antenna. Unfortunately, it doesn't do "ADSB In" to get things like traffic and weather information though. In order to get that capability, you need ANOTHER box, the GDL39R, which connects to a separate transponder antenna. Hence a lot of folks these days, including probably me, need two transponder antennas.

Garmin does make an all-in-one box called the GDL88, but it's a lot more expensive (about $1000 more than the other two boxes combined, if I remember).
