Re: Input Power for Tx for Radiation Pattern Measurement Pur
Important is also the distance between the two antennas (TX antenna and measured antenna).
Assuming a maximum of 10m between antennas, 10dBm should be enough to measure the antenna pattern. The idea is to don’t have deeps in antenna pattern higher than TX power + Horn gain - Path Loss, which makes the signal do drop below noise floor of the Spectrum Analyzer that you are using for measurement.
