Milverton,

Not practical for LF reception.

While the beverage is an excellent and directional receive antenna, it 
must be at least 1 wavelength long to be effective, longer is better.
One needs at least 2 oriented at right angles to cover all directions.
At 160 meters, 1 wavelength is about 530 feet - practical on some lots.  
To have a beverage on 100kHz would require a length of 9540 feet - 
almost 2 miles.  Some ranchers in the US Southwest may have that kind of 
space available, but not on even a large lot owned by a typical ham.

73,
