5.5 SURGE PROTECTION
When installing a VIDA Broadband Base Station, MultiLink Station, or Subscriber Station you should
always install external surge protectors to protect the system components from lightning or transient
damage. Table 5-1 lists surge protectors that have been tested in VIDA Broadband systems and are
available from Harris. Detailed descriptions of these devices can be found in the VIDA Broadband
Installation Manual, MM-014720-001.

5.6 ANTENNA OPTIONS
The VIDA Broadband Client allows users to choose many different antenna types to meet their
application requirements. For fixed installations, a directional antenna can significantly extend the
effective range of the Client. For example, a high gain directional antenna may improve signal quality
over a long distance while antennas with less gain or omnidirectional may perform better in densely
patterned city regions.

patterned city regions.
Three basic methods exist for mounting the base station antenna used with a Client. Two of the three
methods mount the antenna directly on the Client and the third requires a separate mounting location and
hardware. The three methods include the following:

• Direct or remote mounting of an omnidirectional antenna on the subscriber station
• Direct or remote mounting of a directional antenna on the front face of the subscriber station, or
• Direct or remote mounting of an antenna through the connection of an RF cable to the subscriber
