Lightning Protection
As with any tall structure a tower is subject to being a target for lightning. Although a direct hit is catastrophic,
local nearby strikes can also cause equipment failures. Your tower must be properly grounded to help avoid
any damage to your home or radio gear. This includes the rotator control lines and coaxial cables. Consult
other publications with details concerning lightning protection, bonding and grounding.
Any thrust bearing could be welded in place from lightning. To help avoid this problem it is strongly suggested
a lightning rod and bearing by-pass be installed. Reference the following products:

Maintenance
The DX Engineering RT4500HD Rotator is a factory sealed and lubricated unit and does not require any
additional lubrication.
Routine maintenance would be to verify all bolts are properly tightened and nothing has shaken loose over
time from wind and weather vibrations and the bottom weep holes are not clogged.
