The Kathrein Scala Division 840 10291, 840 10292, and 84010293
are ruggedly built broadband, folded dipole Yagi
antennas.Like all Kathrein Scala Division antennas, these
antennas are
made of the finest materials using state of the art
electrical
and mechanical designs, resulting in superior performance
and long service life.
The antennas are black anodized and may be used stand-aloneor in
stacked arrays for higher gain, increased side-lobe
suppression, or custom azimuth patterns.
