The antennas arrived

After a little trouble with FedEx, the four HyperLink antennas arrived (two 30 dBi HG2430G and two 24 dBi HG2424G).

I wasted no time in assembling one of the 30 dBi units and mounting it on the mast I had set up. It took a while, but everything went smoothly. It was bigger than I had imagined, but not as heavy. The whole thing can be put together with just one person, although two would have been easier. It can only be mounted about half-way up the mast because of the guy wires.

I was curious about polarization. On this antenna, the center feed horn can be rotated 90 degrees easily, but I don't see any way to rotate the dish itself without mounting it on a horizontal pipe (and then I would worry about its stability). The antenna's instructions say, "Feed horn must be orientated to grid as shown [feed horn parallel to grid bars] for optimal antenna performance." How much loss are we talking about here? For long-distance links, I suspect that horizontal polarization would reduce interfere from other WiFi signals (which are usually vertically polarized), but it appears that this antenna is only designed for vertical polarization.

Like what we're doing? Pay what you want to support TR and get nifty extra features.
