Ive got a cobra 29 lx and a rci 2950 and only 1 antron. The 29 is for 11M and 2950 is 10M. Is a duplexer what i need to operate both radios on 1 antenna?
And, does the (Radio) im not using, need to be OFF? Or does it matter?

Yes...

and Yes...only need one radio t a time on anyways..and no need for spatter over un used radio by leaving it on and thus also causing feedback likely

I have never seen nor heard of a duplexer for 10 and 11m. The bands are too close for a duplexer to filter and split the two bands. A GOOD switch with high isolation is what is needed and yes, turn the unused radio off.

Alex,...... can I buy a vowel? I'll buy an "A"

All I can say is (1)- It was in the wee hours of the morning on the night shift, (2)- I was at work at the time, and (3)- using a phone online to edit text is not a good idea considering the first two excuses. Now what does that have to do with duplexers? Notice how I changed the subject to divert attention to my glaring error. Thanks for being subtle about it.

No you don't use a duplexer for 10 and 11 meters. I think MFJ makes a switch similar to an antenna switch that lets you switch between several different radios and antennas or just one antenna. This is what you need.
