Figure 2-3. Medium Gain 12dBi Antenna

Medium Gain 18dBi Antenna (Uni-18)

This medium gain antenna has a medium beamwidth (14 degrees) which increases the sensitivity to inaccurate alignment, but decreases the influence of multipath propagation (fading). It is intended for outdoor installations over medium to long distances. It is probably the best choice for most medium to long range applications. UNI-18 Antenna dimensions are: 41 x 51 x 38 cm. (16 x 20 x 15 in.).
