900 MHz Yagi Antennas
A908NJ-DY, A911NJ-DY
The RadioLinx Directional Yagi Antenna can be used as bridge antennas between two networks or for point-to-point communications. The antennas are field adjustable for vertical or horizontal polarization with matched principal plane beamwidth for optimum performance in either orientation. This design also provides improved front-to-back ratio and sidelobe suppression that reduces interference. All models feature a robust mounting structure for consistent performance regardless of weather conditions.
Typically, Yagi antennas compose an array of linear elements, parallel to on another and attached perpendicular to and along the length of a metal boom. Elements on one side of the feed element are longer and act as reflectors. Elements on the other side of the feed element are shorter and act as directors. The antenna radiates in a beam out the end with the shorter elements. Beamwidth varies (longer length produces a narrower beam).
