THE ‘Twin Beam’ models (Type 2240, 2241 and 2243) have

been designed to double channel capacity at busy sites

by replacing the existing single panel. They comprise two

separate dual polar antennas side-by-side in a single

radome. This configuration reduces visual impact and

simplifies installation, providing cost advantages over

separate panels. Model variants are available giving

different gain and electrical downtilt to exactly match

your site requirements. All models feature an vary low

component count and one piece Printed circuit board.

This results in consistently high product quality and

reliability, having an excellent intermodulation

performance. Two connectors for each antenna panel

are provided at the base of the antenna.

The ‘Trisector’ models (Type 2290, 2291 and 2295) have

been designed to provide low visual impact installations

by replacing three existing single panel antennas. They

comprise three separate dual polar antennas in a single

round radome. This configuration simplifies installation,

providing cost advantages over separate panels. Model

variants are available giving different gain and electrical

downtilt to exactly match your site requirements. All

models feature an extremely low component count and

one piece Printed circuit board. This results in consistently

high product quality and reliability, having an excellent

intermodulation performance. Two connectors for

each antenna panel are provided at the base of the

antenna. A number of innovative installations such as

flag pole and street-works are possible with this type of

antennas.
