Grounding the antenna
Follow these guidelines to ground the antenna in accordance with national electrical code
instructions.
Step Action
1
Use No. 10 AWG copper or No. 8 or larger copper-clad steel or bronze wire as ground wires
for both mast and lead-in. Securely clamp the wire to the bottom of the mast.
2
Secure the lead-in wire to a lightning arrestor and mast ground wire to the building with stand-
off insulators spaced from 4 feet (1.2 meters) to 8 feet (1.8 meters) apart.
3
Using coaxial cable, connect the antenna base to the transmitter’s remote antenna connector
(located at top right as you face the transmitter display). Antenna cable shield is bonded to
earth ground via either the transmitter earth ground connection and/or by the lightning arrestor
earth ground connection. The lightning arrestor must be bonded to earth ground in order to
function properly. Tighten cables by hand only; do not use tools or you could overtighten.
See section 3 for cable types and connection information.
4
If the coax cable is to enter a building, then the lightning arrestor should be mounted as close
as possible to where the lead-in wire enters the building. The lightning arrestor sold by
Honeywell features a bulkhead N-Female connector with a rubber “O”-ring seal which can be
used for mounting through an enclosure wall. The lightning arrestor can also be mounted
using the included stainless steel mounting bracket. Both connector ports of the lightning
arrestor provide equal protection no matter which way it is installed. Either port can face the
antenna and either port can face the Transmitter.
5
Drill a hole in the building's wall as close as possible to the equipment to which you will
connect the lead-in cable.
