I'm looking for a high-power wireless network adapter like Alfa products but more powerful. The Alfa AWUS036H is said to be the most powerful one, though its TX power is a little less than Alfa's latest wireless network adapters.
I need a wireless network adapter that has a TX power output of 3W or more and uses USB ports for connection. I'm going to use it on an omni-directional 10W antenna, and to offset the signal loss due to the length of the cable I need a powerful adapter. I don't want to use wireless amplifiers, so the adapter itself should generate the 3W or more.
I've found some 3 or 4 Watt wireless access points from brands like MikroTik but they use Ethernet cables instead of USB. They also operate as a totally different network device and they can't be controlled directly using a computer, so they have many limitations.
