Grid 24dBi 2.4GHz, Alfa 36NHA, L-400 40FT SMA Cable ...




This is the popular 24dBi grid parabolic WiFi antenna which provides up to 8 miles of range. The 2.4Ghz grid antenna is compatible with WiFi standards 802.11b, 802.11g, 802.11n for fast data transfers up to 150mbps. Also, the grid antenna has a very narrow directional WiFi pattern at just 7 degrees wide which translates into a high 24dBi gain rating. To see exactly what the signal pattern is doing click the "Additional Info" tab.

This 24 dBi WiFi is the parbolic antenna which can provide up to 8 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 14" 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.

Please note that all Wi-Fi antennas require a cable extension. Please choose a link to choose the right cable for you.
