Directional Antennas.

Directional antennas can be a:

• Yagi antenna with a main beam and orthogonal elements, or

• Directional radome, which is cylindrical in shape, or

• Parabolic antenna.

A directional antenna provides high gain in the forward direction, but lower

gain in other directions.This may be used to compensate for coaxial cable

loss for installations with marginal radio path.

Yagi antennas should be installed with the main beam horizontal,pointing

in the forward direction. If the Yagi is transmitting to a vertically mounted

omni-directional antenna, then the Yagi elements should be vertical.If the

Yagi is transmitting to another Yagi,then the elements at each end of the

wireless link need to in the same plane (horizontal or vertical).

Directional radomes should be installed with the central beam horizontal

and must be pointed exactly in the direction of transmission to benefit from

the gain of the antenna. Parabolic antennas should be mounted as per the

manufacturer’s instructions,with the parabolic grid at the “back” and the

radiating element pointing in the direction of the transmission.

Ensure that the antenna mounting bracket is well connected to

“ground/earth.”

2.2 Power Supply

The BU-245U-E module can be powered from a 9 - 30Vdc power supply.

The power supply should be rated at 1 Amp.The positive side of the

supply must not be connected to earth.The supply negative is connected

to the unit case internally.The DC supply may be a floating supply or

negatively grounded.

The power requirements of the BU-245U-E unit are shown in the

following table.

TX @ 400mW 340mA 180mA 410mA 210mA

A Ground Terminal is provided on the back of the module.This Terminal should be connected to the Main Ground point of the installation in order

to provide efficient surge protection for the module (refer to the Installation Diagram).
