2.5.3.4 Antenna Planning
Larger antennas have the advantage of providing narrower beamwidths and high isotropic gain,
which yields better link performance (higher fade margin, better availability), and improves
immunity to spatial interference (due to the smaller beamwidths). However, larger antennas are
more costly to purchase and install than smaller antennas and in some cases, they require
special equipment for installation due to narrower beamwidths. They are also more easily
affected by wind.
Only directional antennas can be used with the Challenger L Digital Radios. Consult factory for
antenna manufacturer options.
1. Select where the cable will enter the building from the outside.
2. Determine the length of cable required. Allow three extra feet on each end to allow for strain
relief, as well as any bends and turns.
