Operating instructions
Up to 12 Radios –
Advanced tower installations with many pan and tilt units will require careful planning and assessment by a qualied radio technician. Videolarm recommends utilizing
the manual channel mode; antennae gain of 11dBi and mixed polarization between channels. It is recommended that antennae maintain a minimum of 4 ft of physical
separation and are oriented with greater than 45° of angular separation. If 45° of angular separation cannot be met, then it is recommend a minimum of 12 ft of physical
separation. Antenna polarization should be utilized to minimize adjacent channel saturation. Off-riggers and/or cavity lters might be necessary to achieve maximum
range with all 12 radios operating simultaneously from the same tower.
