This antenna has a radial gain of up to 7 dBi and therefore a much greater range than the FA250 radio antenna. The reception power in the extension of the antenna axis is significantly lower. This must be taken into account when placing it. It may only be used as a receiving antenna. Antenna height 59cm. With SMA screw connection. Extension by 5m with the FAV5 radio antenna extension or by 10m with FAV10.
