WISCO International (Decibel Products - Directionals ASP816-817)

ASP816 3 or 5 ELEMENT YAGI ANTENNAS
ASP817 7 or 9 dB GAIN, 138-174 MHz

ASP816

Extended Range 3 and 5 element parasitic yagis provide maximum directional gain.
Field Tunable fully tunable across entire frequency range allows yagis to be purchased in anticipation of frequency requirements.
Interference Eliminator high front-to-back ratio protects systems from unwanted signals in opposite direction.
Rugged heavy-duly construction includes gold iridited boom and elements for maximum life.
Versatile use for point-to-point applications, selected area coverage, reduction of noise and offending signals, and combining with omni antennas for special keyhole patterns.
