My consulting practice in the design of large sound systems bought an 
expensive unit (about $2K 20 years ago) that worked in the range of 2 
kHz. It stayed on my shelf when I closed the business about ten years 
ago.

Virtually all ground resistance measurements I'm aware of are done at 
either power or audio frequency.

Note that, except for some receiving antennas, the sole reason for an 
earth connection is safety, primarily lightning, but also from issues 
with mains power distribution. An earth connection does NOT make 
antennas work better, nor does it reduce noise. What DOES matter a LOT 
is proper bonding of all the grounds in a home or other building.
