The range can be better for sure. One thought is to:

On modules without PA/LNA, start by soldering a 10uF ceramic SMD cap directly to the VCC/GND header pins. Then, connect the module’s VCC and GND each through a 1ohm resistor; which in combo with the added cap, makes a more effective Pi filter.

For the modules with PA/LNA, I use 100uF and 2x 0.1ohm. Plus I usually add a LC Pi filter on the switcher output.

Also, could build a more proper LC filter: http://blog.blackoise.de/2016/03/building-a-lc-filter-for-your-nrf24l01-palna-module/
