The output power of Basic TX is about 0.5 mW, and it is too low for air transmit. Your gain booster sounds just fine, and it should do the trick. But can you tell what frequency you are trying to transmit and does your booster operate on that frequency? Also, it would be good idea to use /usrp_siggen/.py to generate sin-signal and measure the output power of your booster. Note that /usrp_siggen/.py has amplitude (-A) parameter that you should set to 32000 to get the maximum power output from Basic TX.
What kind of antennas you have?
