So the next best way is to use a Vector Network Analyzer (VNA) to check the frequency response of the antenna over a spectrum (band) of frequencies. The best way to check radiated power, gain, and directivity is in a anechoic chamber but that is difficult and expensive.
This may use a VSWR or SWR (for both voltage and power) meter and/or a power meter.Īlthough these are the preliminary ways to check and are included on some RF transceivers to see how well you coax and antenna 'match' the output impedance of the transceiver, its not the best way to see if your antenna is either a good antenna or if its effective for radiating power.
Although there are many ways to check to see if your antenna is working properly, the tow most common are to check the Voltage Standing Wave Ratio (VSWR) as well as the Reflected Power vs the Output Power.
