Protecting antennas: Part 2
Looking at the damage done to a protected antenna over time.
A while back, we looked at how an antenna structure was provided with a protective, cylindrical enclosure.
Taking another look via Google Maps, we find an image of the protected antenna in Baldwin, NY when it looked like Figure 1.

I drove past this location on October 26th, and this protected antenna now looks like Figure 2.

The larger diameter section of the protective shroud has fallen off. The antenna elements themselves and their cabling are now in view.
Presumably, this will soon be repaired but the mishap does offer a brief (we hope) view of the goodies.
