Site 1 and two are linked via Point to Point for greater distances
Figure 25.
Tip: The majority of Bridge links are done from building roof tops saving the expense of a
radio tower and professional climber or bucket truck.
Different Antenna options for use with Bridge 1400 series
Figure 26.
As the radio energy is focused using different antennas the coverage pattern or angle in which of the
radio signal propagates changes, this is known as the antenna beamwidth. When using the 9 dBi
antenna it will transmit with a horizontal beamwidth of 360 degrees going in all directions, this will
certainly cause the radio waves to disperse the power in all directions therefore it would not go
nearly as far as say a 28 dBi dish antenna with a narrow beamwidth of only 5.7 degrees.
