(15dBi) and controllable transmission patterns.
This antenna must be carefully aligned for long
distance applications. The Beamwidth of the Yagi
is 30° Elevation, and 34° Azimuth. The Yagi is mast
mounted for masts up to 2-1/8” (5.4cm) in diameter.
The Yagi is connected to CellScale equipment with
adapter coax P/N 12751 (6’, 1.8m) or P/N 13209

cables longer and keep the Coax short.
