Hi,
I'm using RFM69HCW 915 MHz Moteino Mega-USBs, ATC is not enabled. One Mega has a standard quarter-wave wire antenna and the other has one of Captcha's dipoles attached via an 8.25 inch coaxial cable. One Mega is powered with two AA batteries through VIN and the other is powered by USB (laptop). With this setup I get an RSSI of -69 at only 120 feet, line of sight and clear of obstacles. I need the range to be much greater, 1000 feet.
(I previously used a quarter-wave antenna on each Mega, but thought I'd try adding a dipole to one. RSSI improved some, but not as much as I need.)
The following lines are included in the sketch (among others of course):
#define FREQUENCY RF69_915MHZ
#define IS_RFM69HW
#define SERIAL_BAUD 115200
void setup() {
Serial.begin(SERIAL_BAUD);
delay(10);
radio.initialize(FREQUENCY,NODEID,NETWORKID);
#ifdef IS_RFM69HW
radio.setHighPower();
#endif
}
I haven't changed any default radio settings because I don't know how and wouldn't really know what to change.
Is there anything wrong with the definitions listed above?
I'm looking for some advice to get the desired 1000 feet range. Thanks!
