This 21 dBi WiFi is the compact parabolic antenna which can provide up to 5 miles of signal transmissions and receptions (provided proper height, obstruction clearance, power and antenna on other end). The WiFi dish has a parabolic grid made of cast aluminum then powder coated in a light gray finish making it very weather resistant. The feedhorn arm is a 10" long support for the dipole/reflector assembly. It is easy to mount on a suitable TV antenna mast, water pipe or other support tube. Adjustable elevation angle is possible via the U-bolt mounting system.
