nRF24L01+PA+LNA

I found the individual nRF24L01 modules and the 16dbi antennas cheaper seperately. Are the circuitry of both the integrated module and the external antenna module same? If same how should I connect the 16 dbi antenna to the module externally as I want to increase the modules' transceiving range?

Why doesn't anyone reply ?????????????????????????????????!!!!!!!!!!!!!!!
