Goto http://www.timesmicrowave.com/cgi-bin/calculate.pl and plug in the 
numbers.  10 feet of LMR-195 will give you ~2dB of attenuation at 
2400Mhz.  With a 10dBi antenna you'll get ~8dBi, probably less if you 
consider signal loss from the connector.

What kind of omni is it? Did you play with the position?  Does the 
antenna have sufficient grounding?

I have a 5dBi mag mount antenna from Hyperlink, also using LMR-195.  
I've found that there is a particular sweet spot on my car's roof that 
gives me an extra 2dB of signal compared to other mounting locations.  
Move the antenna around, if its a mag mount try sticking it on 
something large and metal, see if it changes anything.
