I thought it wasn't necessary either honestly 😂 The boss wanted it though.
It was on site at a 300m tower, in a leased room for our equipment. There was a lot of other things at that location too, terrestrial TV & Radio broadcast, other microwave links, cellular stuff as well, even some ham stuff I believe. The boss had 20 years experience though, and it was replicating the setup from our initial location which had a similar set of conditions. I'm sure he had his reasons.
