the RF Explorer WSUB1G+ if you can get the proper antennas for it.
these may cost more than the meter itself.

In the range from 50 KHz to 2 MHz you need a ferrite bead coil type antenna as well.
I am still looking out for cheap antennas that do the trick well enough for my purposes before getting also this new meter, which looks handy and useful within an important frequency range where most emf-detectors or -analysers do little or nothing.

i found another antenna for it, must search for the model again.

this is the newest rf explorer, from 50 kHz upto 6GHz :

it looks great for its price ( including european value-added-taxes here, you may get it cheaper ).
do not expect a fast sweep.
with a bunch of additional antennas, it could be useful.
