YBN 850-5 Yagi



Small LTE Low Noise Yagi covering 800 to 860 MHz LTE band

Emphasising a relatively high directivity factor for its size over an extraordinary bandwidth predestinates this design to boost the signal-to-noise level in difficult spots for reception or to manage a connect at all in rural places.
