The aerial element for the electric field signal

The aerial element can be constructed from RG-58 coax and a BNC connector. The length is not critical. Match the length of the upper section to the length of the PVC pipe. Add on an additional length to reach the preamp. Keep the length of coax, from the BNC to the point where the outer braid is cut, as short as possible.

An alternative aerial option would be to use a commercial CB whip style antenna. Locate the VLF pre-amplifier at the base of the antenna. Connect the preamp to the antenna via the shortest length of coax practical.
