I need a favor. I cannot send a message out to the Phys-L list because I am
not at my office where the list will accept my messages. If you would post
the message below I would appreciate it. The subject might be "connecting
cable".

I have an inexpensive Panasonic stereo and do no use it much because I live
at the bottom of a valley and cannot get good FM reception. To remedy this
situation I intend to install an antenna and connect it using 75 ohm coaxial
cable. However, I am unsure as to how to connect the cable to the stereo.
The back of the stereo has a pair of antenna connections. The phrase 75
ohms sits above them and one connector has a ground symbol below it. Each
connector holds onto the wire when a lever is lifted into place.
Should I just put the braided outer connector into the connector with the
ground symbol and the center connector into the other connector, or what?
One options would be to attach an F connector to the end of the cable and
use a 35 ohm to 300 ohm transformer to connect it to the stereo. However,
this seems wrong since the stereo clearly indicates that it expects a 75 ohm
impedance. What to do?
Also, I went to radio shack and looked at the back of several stereos as well
as at the instructions that come with them. This resulted in additional
confusion on my part. Some of the instructions showed three connectors, one
for 75 ohms an two for 300 ohm. It seems to me that one connector is not
adequate since that would leave the outer conductor of the coaxial cable
floating. How does one interpret such instructions?
