Why is the Ferimex AP/Client Antenna easy to install?
The AP/Client Antenna 11g + PoE is a completely integrated product which needs only an ethernet cable to go inside the building. The power to the device and antenna is supplied by Power-Over-Ethernet using a regular ethernet cable. If you used a regular antenna and a device, you would need thick cable from the antenna to the device inside the building, possibly requiring large holes to be drilled. You also would need a pigtail from the cable to the device, and ethernet cable from the device to the computer. Or you would have to install power outside the building.
