Did you actually read the description ?
Why would an amplifier designed for 3.5Mhz to 30Mhz be suitable for a NRF2401 ?
If your thinking of desinging your own long range radio control system, you need a real good understanding of things RF.
There is the safety issue to consider, its not a good idea to build an RC system and have the drone\plane fall out of the sky at random due to inadequate design.
