Preparing for Installation
Check the System
Remember!
It is YOUR responsibility to ensure that your installation meets all
applicable codes and the centerline-of-radiation requirements of
your FCC construction permit.
Shively's factory designer has planned the installation of the antenna
based upon information provided by you. If this information contained
errors, the parts and mounting hardware will have been designed
incorrectly and will cause expensive delays in installation.
Therefore,
we recommend that you recheck the installation parameters during this
planning stage.
Check all the parts to be sure that they will fit the tower and each
other. Study the installation drawings carefully to confirm that the infor-
mation used in designing the antenna and mounts was, in fact, accu-
rate.
Have a reliable tower person, familiar with antennas and coaxial line,
inspect the tower and review the installation drawings before the full
rigging crew arrives.
If design problems are found, contact Shively Labs immediately. Pay
particular attention to:
• Frequency of the antenna.
• Fit of the mounts to the tower members.
• Freedom from interference by gussets, leg flanges, guys and their
attachment points, tower face members, obstruction lights, and
other components.
• Compatibility of transmission line and antenna input terminals.
• Location of the transmission line run relative to the antenna input
terminal.
• Use of non-metallic guy sections on the tower in the region to be
occupied by the FM antenna. Ensure that there are no metal guys
within ten feet (three meters) of any radiator.
• Availability of proper electrical service for deicers, if applicable.
• The adequacy of the tower structure and guys to carry the windload
placed upon them by the antenna.
You gave Shively this information at the time of purchase, but a last
check at this time can catch an error, which will be easier to correct
before installation begins.
