When you say "Screw on" do you mean two ordinary screws? For 300 ohm twin
cable?
No; I mean that the input is threaded, for a standard cable TV cable.
The antenna cable is not threaded, and it will connect, but only
imperfectly. The salesmen at both Circuit City and Radio Shack, who may
be bullshitters, told me that you just stick in in there and wiggle it
around until you are satisfied with the results.
Up until this morning, I was convinced that the problem was solved, but
now I am having picture problems, which also seem to be
antenna-related: if a human being is near the antenna, the picture
becomes much clearer, but if said human moves away, the picure becomes
blurrier.
I live at the bottom of a hill in L.A., and I have been told that this
is a problem for reception. I bought the $20 Terk antenna to replace my
generic rabbit-ears antenna, and initially the picture was very good.
This antenna stuff mystifies me. Does reception change with the
weather, or cosmic rays, or things like that?
The problem may also lie with my bargain-priced 13" Magnavox, which is
now two months old. Interestingly, the sound problem is completely
gone. Now it's a picture problem.
