Bridge Link Planning
(7.5 ft) mast or pole must be contructed on its roof to achieve the required antenna
height. Building B is only three stories high, or 9 m (30 ft), but is located at an
elevation that is 12 m (39 ft) higher than bulding A. To mount an anntena at the
required height on building B, a mast or pole of only 1.3 m (4.3 ft) is needed.
Warning: Never construct a radio mast, pole, or tower near overhead power lines.
Note: Local regulations may limit or prevent construction of a high radio mast or tower. If
your wireless bridge link requires a high radio mast or tower, consult a
professional contractor for advice.

Antenna Position and Orientation

Once the required antenna height has been determined, other factors affecting the
precise position of the wireless bridge must be considered:
• Be sure there are no other radio antennas within 2 m (6 ft) of the wireless bridge
• Place the wireless bridge away from power and telephone lines
• Avoid placing the wireless bridge too close to any metallic, refective surfaces, such
as roof-installed air-conditioning equipment, tinted windows, wire fences, or water
pipes
• The wireless bridge antennas at both ends of the link must be positioned with the
same polarization direction, either horizontal or vertical
Antenna Polarization — The wireless bridge's integrated antenna sends a radio
signal that is polarized in a particular direction. The antenna's receive sensitivity is
also higher for radio signals that have the same polarization. To maximize the
performance of the wireless link, both antennas must be set to the same polarization
direction. The unit should be mounted with the antenna sockets facing upwards.
Antenna sockets should
point upwards in a vertical
