I'm very new to AM. :wink: I thought with the spectrum analyzer and a calibrated antenna, I can have an accurate field strength reading just like the Potomac FIM. Besides, are there any guidelines or standards for measuring AM field strength? I want to...

Antennas for Field Measurement

If I want to carry field measurement with the spectrum analyzer, what types of antennas am I looking for? A calibrated shield loop? Active or Passive? How about for drive test measurement around my town, a monopole? How's the sensitivity of monopole on AM? Do I need an active one? Appreciate for you...
