Drakus' WiFi

WISP Router (wisp-router.com) sold me a RooTenna and an Engenius C3B for about $200. The antenna has about 19dB of gain and space for the C3B radio to fit inside. There is very little signal loss when the C3B (the radio portion) is at (inside) the antenna. The antenna is described as directional but it does have a fairly wide sweet spot. It takes 12vdc power and outputs ethernet connectivity. Ethernet hookup means easy connection to your machine.

ECB-3220 below. This is the higher power, 400mW, new improved version. This is what goes inside the RooTenna, sans rubber ducky.


Darn, I've got this stuff below and don't know how to delete it. Suggestions welcome. Doug
