""Lots of common mode impedance between the ground system and RX Antennas will help that though too."" Dan I run my cables inside galvanized water pipe buried 8", the metal shield magnetic field and electrical field. PVC pipe or direct bury does not protect you from magnetic field, in special from lightning strikes. Common mode noise can be reduced with proper isolation from both electrical and magnetic field. 1000 ft is still too close for top band.
