5. Antennas This section contains important information for using dipole and collinear antennas For more information see the next sections Dipole Antennas Unity gain dipole antennas are commonly used on unlicensed channels The dipole antenna does not provide any gain so the power transmitted from the antenna is the same as the power out of the module A dipole antenna that comes supplied with integral 15 ft cable does not require additional coaxial cable You should mount dipole antennas vertically preferably no less than 1 metre away from a wall or mast for maximum performance Collinear Antennas Collinear antennas transmit the same amount of radio power in all directions horizontally and are easy to install and use They provide gain by compressing the radiated signal to a flattened disc shape and reducing the amount of signal radiated above and below the horizontal plane Collinear antennas are generally used at a central site with more than one remote site or at a repeater site Collinear antennas are similar in appearance to dipole antennas however the antenna is longer Collinear antennas are supplied without cable and require additional coaxial cable You can use collinear antennas to e Transmitter to compensate for the losses in long lengths of coaxial cable e Receiver to increase receive sensitivity 3A1580Rev1 6 www cooperbussmann com BussmannWirelessResources 11 Cooper Bussmann BU 905U L Wireless 1 0 Installation
