Harvestore WISP Install

Over the years many MidWestern WISPS have fashioned ways to use Harvestore silos for broadcast locations. With the help of one of our good clients, who did most of the work designing this, we were able to install a very solid structure on the top of a silo. Please note.

80GHZ microwave antenna alignment (and other mm-wave radios)

Recently we had a teaching moment for a couple of folks who had not had much experience with aligning higher frequency antennas with very tight beamwidths. This particular day we were aligning 2 foot Siklu 80GHZ antennas. One of the questions we often get asked is how do you align these?
