You can't have any of the white part (tip) of the antenna longer (or shorter) than 31.23mm, which is the proper length for the 2.4GHz wavelength. You CAN have longer coax before the antenna tip though. You will see about 0.75dB attenuation for every 12" of coax length. Your antenna (white tip) length is by far more critical. You can have several feet of coax length which is result in a drop a few dB in receiver sensitivity. When it comes to receivers and their sensitivity, every 6dB of gain doubles the effective range. This also applies to loss. So, you don't want much loss anywhere in your setup, but using longer coax lengths (which are not a normally stocked item by anyone) would work.
