Figure 8 Yagi Antenna Mounting
For a two-station installation with both modules using Yagi antennas, horizontal polarization is recommended.
If there are more than two stations transmitting to a common station, the Yagi antennas should have vertical
polarization, and the common or central station should have a collinear (non-directional) antenna.
NOTE Yagi antennas normally have a drain hole on the folded element. The drain hole should be located
on the bottom of the installed antenna.
