Hi Dave,
We were using a 3 ft. whip with a high impedance preamp into a Perseus
receiver. The antenna system was mounted on the car using a mag mount.
I use a similar setup with an SDRPlay receiver. Since the antenna
system is broadband, you don't have to worry about a frequency sensitive
antenna factor affecting your readings. One concern is that the
receiver/preamp does not being overloaded with strong broadcast
stations. We built our preamps with attenuation in the AM and FM
broadcast spectrum.

Hi Tom,
I assume you were using SDR, could you expand a bit on your setup
please... I will be putting together a SDR radio for RFI location
later this year, and any tips would be appreciated. I am looking to
use a RPI, and one of those little dongles, and a downconverter.
