Installation tips

Connections between the antenna and coaxial cable should be carefully

taped to prevent ingress of moisture. Moisture ingress in the coaxial cable

is a common cause for problems with radio systems, as it greatly increases

the radio losses.We recommend that the connection be taped, firstly with

a layer of PVC Tape,then with a vulcanizing tape such as “3M 23 tape”,

and finally with another layer of PVC UV Stabilized insulating tape.The first

layer of tape allows the joint to be easily inspected when trouble shooting

as the vulcanizing seal can be easily removed.

Where antennas are mounted on elevated masts, the masts should be

effectively earthed to avoid lightning surges. For high lightning risk areas,

surge suppression devices between the module and the antenna are

recommended. If the antenna is not already shielded from lightning strike

by an adjacent earthed structure, a lightning rod may be installed above

the antenna to provide shielding.

Omni-directional Antennas

An omni-directional antenna transmits the same

amount of radio power in all directions - as such that

are easy to install and use.The dipole antenna with

integral 15 ft (5m) cable does not require any

additional coaxial cable; however a cable must be used

with the collinear antennas.

Omni-directional antennas should be mounted

vertically,preferably 1 wavelength away (see drawing

below for distances) from a wall or mast and at least

3ft (1m) from the radio module to obtain maximum

range.
