Hi,
I have a Kenwood R-5000 and I have a long wire antenna. There are
two screw terminals in the back of the receiver for a wire antenna.
One screw is labeled: "50 (ohms)" the other screw is labeled "500
ohms" which is the proper lead for a wire antenna?
Thank you,
Mike McM.

Use coax for connection to the 50 ohm terminal and GND. For coax the
outer shield is connected to GND and the coax center wire would be
connected to the 50 ohm terminal. Most coax is 50 or 75 ohms.

Single wire antennas are in the hundreds of ohms. You can connect the
signal wire antenna directly to the 500 ohm terminal. If you do this
though you should connect a ground to the GND terminal. The ground
should be a ground for the antenna only. You can connect a wire to this
ground terminal to a ground rod out in the yard. This will work well if
you are in a low noise area. If you have many RF noise makers in your
house then you might want a different connect scheme. Let us know how
this works for you and if you have noise problems people in the news
group can make more suggestions.
