I'm trying to build a weather station, and this is the last part that I need to complete.

My assumption is that you want to measure wind speed by building an interrupt driven counter. Paul's FreqMeasurement lib may be a bit of an overkill, IMO.

Keep in mind that the Arduino code runs in a slice of the uC time... the RF/protocol/housekeeping routines get called with each iteration of loop{} OR when you do yield() or delay(0) but the native code needs to be dormant less than 50mS before the Arduino code is interrupted.
