Both have low radiation resistance. But, the loop is more often used to determine EM field strength. You just need the right "fudge factor" to convert antenna voltage tto field strength or vice versa. Best regards, Richard Harrison, KB5WZI ===================================== For the very last time I will repeat my question :- "What is the voltage measured between the bottom end of a 1 metre vertical antenna and ground when the field strength is 1 volt per metre. The height (length) of the antenna is much less than 1/4-wavelength. The bottom end of the antenna is immediately above the ground. The ground is assumed perfect. The field is vertically polarised. Frequency, loops, reactance, radiation resistance do not enter into the argument. No other information is needed. Terman, Kraus and Balanis' bibles provide answers to a different question in which I am not interested. Mere mention of these learned gentlemen only confuses the issue. The answer is entirely fundamental to e.m. radiation and reception. All I need is a number of volts. What is it please? ---- Reg, G4FGQ. |
