13.4 Deployment Considerations

The majority of radio links can be successfully deployed with the PTP 300 Series. It should only
be necessary to use external antennas where the Link Estimator indicates marginal performance
for a specific link – for example when the link is heavily obscured by dense woodland on an NLOS
link or extremely long LOS links (>80km or >50 miles) over water.
The external antennas can be either dual-polarization (as the integrated antenna) or two single
polarized antennas can be used in a spatially diverse configuration. It is expected that the dual-
polarization antennas would normally be used to simplify the installation process; spatially diverse
antennas may provide additional fade margin on very long LOS links where there is evidence of
correlation of the fading characteristics on Vertical and Horizontal polarizations.
