I want my n/ac Wi-Fi card to operate in a spatially directional manner. To achieve that I want to use a directional antenna(s). There is a slight complication though, because my Alfa AWUS036ACH network card has two omni-directional antennas.
Because of that, I'm confused on how I should connect a directional antenna to such a setup. I can imagine a few options, but I don't have the experience to judge what would give me the optimal gain in dBm.
I can see the following options:
Connecting two directional antennas and pointing them in one direction. The problem here is that the antenna connectors are very close to each other and two directional antenna would not fit that close together. So, I would have to extend connector using cables and build some frame to hold the antennas. A lot of work, and cables incure signal loss.
Disconnecting one omni and connecting one directional. Problem here is that I don't know if the NIC can work using one antenna.
Connecting multipatch antenna -- quite expensive, but if that is the only option then I have to go with that.
Or maybe some other option?
