Installation Planning 27
External Interference: Because the Link CX operates in an unlicensed band, interWAVE
strongly recommends that you use a spectrum analyzer at both ends of planned radio links,
with the receiving antenna as close to the proposed Link CX antenna mounting spot as
possible. Use a polarized antenna, and scan for both horizontally- and vertically-polarized
interfering radiation. If you find external interference in either of the two (High or Low)
bands, configure the Link CX for the least-impacted band. Refer to Table 3-3 for the High
and Low bands for the Link CX radio.
