Review installation considerations
Antenna mounting
Mount antenna vertically (±5°)
Antenna height
Mount antenna 14 feet (4.3 meters) above infrastructure with clear line of sight.
Affix coaxial cable
Ensure that coaxial cable is securely affixed to the mast to avoid excessive cable
movement.
Install coaxial drip loop
Ensure a drip loop is installed not closer than 1 foot (0.3 meters) from the transmitter. It
may also be convenient to affix the drip loop to the lower portion of the mast ensuring
that condensation or rainwater will flow away from the coaxial connections.
