Excellent Omni Antenna!

This 7 dBi dual band omni antenna works great like so many Alfa products I've bought over the years. Using Alfa's powerful ACHM adapter with it, I can connect to 2 hotspot signals on the 5 GHz band, each of which is approximately 1/4 mile from where I'm at, with good stable connection to the Internet. Another high-quality product from Alfa. :)
