Alaris Antennas Foldable High-Power LPDA Antennas

150

Alaris Antennas has a new range of Foldable High-Power Log Periodic Dipole Antennas (LPDA)s which cover a wide range of frequency bands. The antennas can also be customised should the user require a different frequency band to be covered.

LPDA in deployed configuration

Alaris Antennas’ LPDAs provide a low and stable VSWR across the wide band of coverage and are in most cases capable of handling continuous power inputs of 1000 W or more. The antennas can be deployed in either a horizontal or a vertical polarisation configuration.

The new range of LPDAs are unique in that they have foldable elements which allow the antenna to be deployed and stowed within a few minutes, without requiring any additional tools and without having to remove any parts from the antenna.

The folding mechanism allows for easy deployment on installations where the operator has limited room to manoeuvre and to easily do so whilst wearing protective gear such as cold weather gloves. These antennas are ideal for installation on vehicles or shelters.

The range of antennas include full size and reduced size antennas which allow the user to do a trade-off between performance and system installation limitations.
