TD WL-4
TD WL-4
Constant Directivity Horn
KEY FEATURES
•   Designed to be used with two WL-4 wave guides
•   It provides uniform response, on and off-axis
with a neutral and natural frequency reproduction
•   Coverage angles of 90? in the horizontal plane
and 20? in the vertical plane
•   Precise directivity control in the pass band
•   Cast aluminium construction
GENERAL DESCRIPTION
This horn has been designed to work specifically with two Beyma WL-4 wave guides providing uniform on and off-axis response.
The constant directivity characteristics of this model ensure the ability to cover 90? wide horizontally and 20? wide vertically, at
virtually any frequency within its operational range. To ensure freedom of resonance, this flare is constructed of cast aluminium,
with flat front finish to facilitate flush mounting.
