Can you be more specific than simply saying

but against the same problem
You said at the start:-

It loose signal very often so I soldered a 100uf ceramic capacitor and works pretty good but it rarely loose the signal again what can I do for this problem?
So what is the same?

We need to see now the full schematic, and your sketch for both send and receive and the errors you are getting.

When I soldered 10uf  electrolytic capacitor parallel with 100nf  ceramic my sketch saws me on serial monitor more "radio no available "

The radios need a power supply capable of supplying 200mA at 3.3 Volts.  Caps will not fix a supply that can only supply 50mA.

In other words I need a power supply

Hi,

Can you please post a copy of your circuit, in CAD or a picture of a hand drawn circuit in jpg, png?
Also a picture of your project thanks.

Tom..... :)

On pdf of nrf it says 14ma...
I'm from mobile and I don't know how to upload photos but I have connected nrf on arduino nano (it's clone from eBay )

The 100K is not a multiplier. The K is the material the cap
is made from. It is most likely even smaller than 100nf. It is
most likely 100pf.
Electrolytics have poor high frequency response above a megahertz
or so. Tantalums are better but hard to find in sizes over 10uF for cheap.
Putting ceramics in parallel is typically done on electrolytics.
