Antenna Assembly
(1) Remove antenna from package and adjust elements to proper position. You will find a small mark on the center of each
element to aid in its positioning. Tighten each wingnut after verifying proper positioning.
(2) Weatherproofing connections. As coaxial cables tend to absorb moisture through their connectors, it is recommended
that the connector be sealed. There are several products available for this purpose, including a good grade of electrical type
or a rubber compound tape.
