Antenna Mounting

Figure a Figure b Figure c Figure d

The above diagrams show some typical examples of antenna mounting.

a. Not recommended. The mounting pole will have an effect on the

antennas performance and could cause reflections.

b. This is the preferred arrangement where the antenna is clear of the

mounting pole.

c. Not recommended. Although in this position the antenna may work,

especially if the radio path is away from the wall, the proximity of the wall

can cause adverse effects. Many walls, for example, have steel reinforcing

or even metal cladding.

d. This is the preferred arrangement with the antenna clear of the

building. A small pole mounted on ‘A’ brackets may be required to clear the

roof overhang, as shown.

Antenna Types and Performance

Any of the following antennas may be used in combination to give the best possible

link quality. Always make sure that the polarity is matched i.e. both vertically

polarized.

High gain antenna, such as the 20dB Panel, should only be used on the receiver. A

small amount of gain is acceptable on the transmitter to compensate for cable losses

providing the ERP (maximum output power at the antenna) does not exceed the limit.
