Remote Antenna Installation
When installing a remote antenna system, always include a lightning arrestor or coaxial surge suppressor in the system. Remote antenna
systems installed without surge protection invalidate the Banner warranty of the DX80 family of devices. A remote antenna system is any
antenna system where the antenna is not connected directly to the radio and typically use coaxial cable to connect the antenna to the radio.
Surge suppressors should be properly grounded and mounted at ground level near where the cabling enters a building. Install the surge
suppressor indoors or inside a weatherproof enclosure to minimize corrosion or component deterioration. For best results, mount the surge
suppressor as close to the ground as possible to minimize the length of the ground connection and use a single-point ground system to avoid
creating ground loops.
For more detailed information about how antennas work and how to install them, refer to the Antenna Basics chapter.
Always install and properly ground a qualified surge suppressor when installing a remote antenna system. Remote antenna configurations installed without surge suppressors
invalidate the Banner Engineering Corp. warranty. Always keep the ground wire as short as possible and make all ground connections to a single-point ground system to ensure
no ground loops are created.
I/O Isolation
When connecting analog and discrete I/O to external equipment such
as VFDs (Variable Frequency Drives), it may be appropriate to install
interposing relays and/or loop isolation devices to protect the DX80
unit from transients, noise, and ground plane interference originating
from devices or the environment. Contact Banner Engineering Corp.
