Appendix B: Using an External Antenna with GINA
GINA User’s Manual
Grounding
Make sure that the antenna system is grounded to protect against voltage
surges, built up static charges, and lightning strikes:
Use No. 10 AWG (5.3 mm) copper or No. 8 AWG (8.4 mm) aluminum
wire or larger as a ground wire.
Secure antenna lead-in and ground wires with insulated standoff insula-
tors spaced 4-6 ft.(1.2 - 1.7 m) apart.
Mount the antenna discharge unit as close as possible to where the lead-in
enters the building.
