What I meant was that if I had to build a dipole then I would have to
calibrate an antenna factor, and in order to do that I would have to build two
identical units, and measure site attenuation. I would only need to use 0 dBm
or even less to transmit, so I don't think that would drive the balun
Fellow List Peoples,
Does anyone know of a place to obtain a good Pink Noise source? This is
the noise specified in EN 60065, EN 55013, EN 55020 for testing consumer
audio type equipment. The noise is bandwidth limited 22.4 Hz to 22.4 kHz
with a max. 12 dB roll-off at the low end and max. 18
Ken,
I am not sure anymore, do you need to measure intensity or generate field (or
both)? You two posts indicate you may have to do both, so my reply was
obviously wrt measuring the field, but now I realize it is not going to help
you to generate field.

Ken,
Why don't you use calibrated short dipole instead, perhaps ~2 cm? You could
run your own calibration in front of a horn antenna, but be careful about the
influence of the leads. The best orientation for the leads is in-line with the
Poynting vector, i.e. perpendicular to both E and H field.

Ed,
Thanks for the info on the Empire Devices dipole. I have both Empire and
Stoddart/Eaton Ailtech dipole sets. I have both the Eaton equivalent of the
EMCO 3115 and a Stoddart original 1-10 GHz logconical or log spiral. The
problem is I need to make field intensity measurements of cell phones
