I have something which I might just be able to use to make and antenna. I have around 20 of the old steel posts they used to and still use to hold up highway signs. They are around 12 feet high each and are very heavy and probably very strong.
Each one has a series of holes formed when they were made. I think I could use them by attaching two or more together and bolting to the side of the eaves after driving the first one into the ground. The only problem is they are really heavy.
I guess I could make a ladder out of them too. It would be extremely stout but also so heavy as to be difficult to move around.
Someplace on the web, I was able to get a schematic of where the best position would be for my antenna. Who knew a horizontal position would make a difference.
Anyways, the Sherlock that I missed, I can watch on Netflex.
Sure interesting characters and the show shoves your brain into overdrive.
