Use a decent 3.3V supply (at least for the high power module).

Please post your code
The easier you make it to read and copy the code the more likely it is that you will get help
Please follow the advice given in the link below when posting code , use code tags and post the code here
have you tried with non-amplified antenna?
I am using rf24 library and running its example code
Which library and example code are you using? Did you double check the pinout?
I used Robin2's simple rf24 tutorial to get my radios to work.
The rf24 radios need more current than most of the 3.3V regulators on Arduinos can supply. A 10uF (min) cap across the radio power terminals close to the module will sometimes help. There are adapters available with a separate regulator.
The high power radios may not work if too close together. Separate them by a few meters.
