That meter is not really a field strength meter, it is just a tuned r-f 
voltmeter calibrated for conducted (hardwired) connections in a 75 ohm, 
closed environment.

But as a rough calibration point, a matched, 1/2-wave dipole with no cable 
loss to the meter input would produce a power level of -44 dBmW when 
optimally oriented in a 100 MHz radiated field of 3.16 mV/m.  That -44 dBmW 
would produce about 55 mV across a 75 ohm measuring impedance (if my 
calculations are right -- somebody pls check me).
