Product Information

These eight element directional yagis are very robust and manufactured to a high degree of Telecommunication specifications. They give a gain of 10.0dB over a 1/2 wave dipole and can withstand a maximum input power rating of 200 watts. The dipole element is made from one piece of tube, thus removing potential high resistance points and the balun is completely seal moulded in black carbon-loaded polyethylene to protect the internal electrical connections. These antennas can be stacked and fed in phase with a matching harness for increased gain.
