I use rg6 flooded for all my low band receive antennas. I usually get it
from dx engineering. I have had very good success with it in the midwest
buried and just on top of the soil. The flooded capability has mitigated
small rodent bites. Some of the antennas I use it with are: 4 square, k9ay,
beverage, bog, and dhdl.
Hope this helps. It is not cheap, however.
