I just printed a dashboard. I still have a margin for improvment but I'm pretty happy with the result. 

Wow, nice. Could you share the file? I could try to edit it for two receivers with thicker design for smaller bags.

I did the same about a year ago and I am very happy with it. Using proper SMA whips with G3 gives me a lot more range. Now I get the first hits where previously the connection would already have dropped completely.
The receiver switches antennae seamlessly, and I get equal level on both of them.

For the first set I used connectors from RS: http://au.rs-online.com/web/p/sma-connectors/5120036/
To mod the rest of my sets I ordered some cheaper connectors from ebay (like these). I cannot make out any difference.

Do not forget to connect ground for the second antenna.

 

Other than the hole for the second antenna, there was absolutely no change to the case. Should I ever feel like reverting to original, its just popping the SMA out and the regular one in.

Using these connectors, you would have to remove a tiny bit of material to fit the original antenna bay:

Hi Sisal,

really nice work. Thinking about the same mod now. I have few questions. How did you connect the second antenna? Did you unconnect the wire going from the antenna output on the PCB to the Jack connector? Did you connect that unused wire on the Jack to the ground or where?

Thanks much! :-)

If a Cos11 is not working due to its connector it's easy to fix it.. try to solder black-white-ground cables to relative pins...done!

If a Cos11 have cable tatters it's easy to fix it with heatshrink.. cover it and heat it....done!

But if a Cos11 is broken from the bottom of its capsule... you have a big trouble.

 

After having dozen of Cos11 broken from the bottom of their capsules during years on set, I had to find a way to fix it.

After some inspectations and workaround, I was finally able to fix all with rebuilding really strong like brand new ones.

 

This is one of them... reconstructed but still naked:

 

I chose different color (gray) for new rubber in order to differentiate it from my originals:

 

Some cosmetic touches have been applied:

 

And finally 4 of them are ready to return back to set...

 

I'm located in Istanbul - Turkey, and may help you if you have a broken Cos11 close to me..

Cheers,

Cihan

Hi, awesome work! What kind of rubber or epoxy you are using to cover the connection?

Thanks!
