anyone know if a comant 2480-201 will fit on a m20e  (replacing the 7 antenna) without extensive mods ?

would really like to avoid punching more holes in the plane for gps antennaes

The CI-196 is the drop in replacement for the 7 antennae. The 7 antennae’s BNC connector is offset.

If you go with the 2480, you’ll probably need to drill 5 new holes, possible 6 if the GPS portion has a separate BNC. Any reason you want a dual antennae over a separate GPS puck?

I can tell you from experience that the addition of my antennae farm didn’t affect my TAS.

Just looked up the footprint of the 2480. You will need to drill new holes for the two BNC connectors and patch the hole left the 7 antenna.

It looks like the hole pattern may be the same. I’ll measure the 7 antenna one I have. If the screw pattern is different then you may need to build a doubler to support it.

Here is another idea. You can do a splitter on the Stratus GPS antenna. That is what they did with my L-3 and GTN.

I’m sure it is legal. My avionics shop is pretty anal about the regulations.

Certainly worth a call to the avionics shop to confirm.
