antennas on a M20K

[flumag]

Hi does anyone has experience with perfect placing antennas on a M20K for:

Aspen Evolution - 2 RSM's

ELT 

L3  - TAS antenna (+ diversity) 

Garmin - 2 GPS antennas

2 COM antennas 

Iridium antenna

There is not a lot of space on top of a Mooney with avoiding interference.

Thanks Hendrik

I recently installed an aspen 2500 with two RSM’s and dual GTN’s. My shop removed the rear top comm antenna and replaced it with a bent whip on the bottom. They said they needed to do this to get proper spacing for the gps and RSM antennas on the top.

They did the same for my com antenna.

I think @StevenL757 had done some interesting studying prior to mounting a few GTN and other Antennae.

Of course, the Longbody does afford some extra area.  But the knowledge of antenna spacing may be quite similar...

Here are some photos of stuff being mounted. Not as much as your setup. You can share a GPS antenna between your L-3 and one of the GPS units.

thats helpful guys. Thanks

I assume one of my comm antenna will need go to the bottom of the plane as well. Not sure about the Iridium at this moment. I keep you update. Maybe it looks more like a hedgehog afterwards. ;-)

COM, antennas can go on the bottom side and will perform equally well.

we getting closer with the antennas. one COM is going to the bottom.

As well as sharing gps signals to save an antenna, you can also combine a comm and gps antenna.

I was thinking about that but decided differently. If you loose one GPS antenna a GPS and the the transponder is gone. Secondly I'm not sure if the splitter is approved by the Garmin STC. Since I had the antennas anyways....
