I, too, have received misleading advice many years ago from the local RS
counter guy, who wanted me to buy a special antenna when color TV came out.
But I fooled him! I painted my antenna in primary colors, red, green and blue,
which really improved color reception. I noticed when watching Fourth of July
fireworks displays that painting my antenna in red, clear varnish and blue
helped a lot, but that when I painted it in red, white and blue that it
improved the black and white reception as well. (This was a few years ago.)
Bow tie antennae have even more uses than reported in this thread. When I
watched more formal programming, such as Masterpiece Theater, reception was
better than with rabbit ears. I attribute this to the antenna matching the
neckwear of the host of the show.
Reference the comments about the consequences from taking advice from outside
consultants: I have also learned (on my own, not from the RS guy) that NTSC is
an abbreviation for more than Never Twice the Same Color. It also means
Never Trust Smiling Consultants.
