I also found out today that, for whatever reason, they DID taper the reflective tape.
Due to images ill post from another computer I thought they put a rectangular piece on and it left a triangular black spot, as opposed to a straight one, on the tapered blade
However after measuring and mocking things up with painters tape, the black shape we see cant be done with a regular rectangular piece of tape. At least not on my antennas
Let me explain. I eyeballed the reflective tape width using a few bts images and electrical/vinyl tape. We can see both ends of the reflective strip on the side facing the camera, right? So i reasonably wrapped the tape around the antenna and cut the tape leaving the right amount visible on our side. I did that at the top and the bottom and got two lengths of tape instead of the same length.
I expected this since it is a tapered pole. A rectangular strip would leave that sort of shape on a cone.. but then I realized
I was measuring the reflective tape, not the space left over!!! (Using black tape to measure the area that was
not black was bound to confuse me)
If it was a regular strip of tape
they would be the same size.
I think they used my biggest diameter, which ended up exactly 1 1/2" and trimmed the other end to what I found to be 1 1/4".... tapering the length.
I think they had 1 1/2" tape but wanted the black strip to run the full length. 1 1/2" would overlap at the tip and 1 1/4" would leave too much black at the bottom, wrapped around the sides .
Today I masked off my blade with 1" tape to paint a black area. I did it larger than I needed so the reflective tape would cover the right area with no gaps, so some paint goes under the tape. The shape it left was familiar but too tapered! Much more angled than the strip we see on set. They cut down an existing strip so the black would be full length and only on one side.
