Base Station Antenna Mounting
To install the Slingshot base station antenna:
1. Verify that the thread on the antenna mount does not extend more than 7/8” [22 mm] to ensure the plastic
inside the antenna receptacle is not damaged when the mount is inserted. If the thread length is longer than
7/8” [22 mm], use two jam nuts to shorten the exposed thread.
2. Thread the metal adapter on the bottom of the antenna onto the mount.
Note: The metal adapter is fixed to the antenna body. Do not attempt to remove this piece.
3. Using a wrench, tighten the antenna adapter to the mount to secure the base station antenna.
4. Remove the dust cap from the TNC connector on the antenna.
5. Attach one end of the provided base station antenna cable to the antenna and route to the selected base
station location.
Note: If the antenna will be mounted on a tower structure, be sure to leave enough slack in the antenna
cable to allow for expansion and contraction of the structure to avoid damaging the cable. Raven
recommends contacting a certified electrician to assist with cable installation and routing.
If the antenna cable will be routed into a building, be sure to use a drip loop to prevent moisture
from entering the building by wicking along the cable. Also be sure to seal any building
penetrations properly to prevent moisture and condensation.
Care & Maintenance
The base station antenna is designed to withstand the elements, including rain, snow, and dust. To ensure that
the antenna continues to perform as desired, keep the radome (top surface of the antenna) clear of snow and
ice and clear any debris as necessary.
Ensure that the TNC antenna cable connector remains clean and dry. If the cable will be disconnected from the
antenna for any length of time, replace the dust cap on the antenna.
