Another common DIY mistake is to believe a spectrum analyser while feeding it through a path /attenuator that overloads the analyser and/or isn¡¯t 50 ohms at the input and/or doesn¡¯t give ?flat attenuation right across the measured frequency range
Accurate Measurement of VHF upward RF power, hand held antenna SWR etc. is ridiculously difficult (but ¡®super simple¡¯ for many YouTubers)?
