nRF24L01+PA+LNA capacitor is used at the power antenna
-
Hello everybody. a capacitor is used to power the antenna?
I have with this transmitter is not more than 100 meters in a straight line. 1000 stated that I need to do to increase the range? I use a 4.7 uF Capacitors staged parallel feeding antenna. arduino pro mini 8mhz 3.3v

Just in case...make sure you use capacitors to stabilize the power to the nRF circuit , not the actual antenna connection.
-
I is powered by a power supply. that is, the capacitor and may not need? on this board serial getaway need the capacitor?
-
@vampircik the caps are needed to smooth your supply to the nrf module.
You also need to make sure that your powersupply deliver enough mA for the nrf module.
My tests conclude that in full power mode the nRF24L01+PA+LNA needs about 100-120mA.
The onboard voltage regulator on the arduino pro mini 3.3V can probably not deliver that much.See also this thread http://forum.mysensors.org/topic/1877/2-x-nrf24l01-pa-lna-with-rf24_pa_max about the problems of a not well shielded nRF24L01+PA+LNA modules.

RelayActuator Using an example. he is originally small power radio. how can it be increased?

// NRFRF24L01 radio driver (set low transmit power by default)
MyTransportNRF24 transport(RF24_CE_PIN, RF24_CS_PIN, RF24_PA_LEVEL_GW);
//MyTransportRFM69 transport;
-
@vampircik you can replace RF24_PA_LEVEL_GW with RF24_PA_MIN, RF24_PA_LOW, RF24_PA_HIGH or RF24_PA_MAX.

As it is written in the sketch? I'm in this weak. It is necessary to have been more powerful.

MyTransportNRF24 transport(RF24_CE_PIN, RF24_CS_PIN, RF24_PA_MAX);
//MyTransportRFM69 transport;so it is necessary to register? all just sort of
