Antenna connection on a Kenwood R-5000?
 

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.

Theoretically the 500 Ohm is for wire antennas. Some radios have better
static protection on one or the other RF input, so that may be a factor
as well.

Mike McM,

On the Kenwood R-5000 Receiver that is the Antenna # 2
Terminal Connections :

Red 500 Ohms Antenna on the Left
Black [GRN] in the Center for Ground
Red 50 Ohms Antenna on the Right

TIP - Make sure that you Select the [ANT 2] Button on the
Front of the Radio to use ANT 2 {Antenna # 2} on the Rear.

First I would recommend that you 'connect' a Ground Wire
to the Kenwood R-5000 Receiver's Black [GRN] Ground
Terminal before you connect any Wire Antenna to the Radio.

The try connecting the 'Long Wire' Antenna first to the Red
500 Ohms Antenna Terminal -and- Then to the Red 500
Ohms Antenna Terminal.

Ensure that you Try this 'Long Wire' Antenna across the AM /
Medium Wave and Shortwave Bands from 500 kHz to 30 MHz
Recording your Reception and Signal Levels for each Band.

* Most of the Time you will find that a 'Long Wire' Antenna
gives the best performance when connected to the Red 500
Ohms Antenna Terminal with a Ground connected to the
GRN Terminal.
* -But- You may find that for your Radio and 'Long Wire'
Antenna you get the best performance when connected
to the Red 50 Ohms Antenna Terminal with a Ground
connected to the GRN Terminal.
-note- You will not know until you try both Red Terminals.
* * Or that on some Shortwave Radio Bands the 500 Ohm
Terminal -or- the 50 Ohm Terminal works better - who knows.

BACK OF THE RADIO MATCHING TRANSFROMER :
Build a simple Back-of-the-Radio Matching Transformer
using an old 3~6 Inch Ferrite Rod from an AM/FM Radio.
* Ferrite Rod that is 3 to 6 Inches long.
* 30 Turns of Red #24 Stranded Hook-Up Wire wrapped
tightly and evenly and centered on the Ferrite Rod.
* 10 Turns of Black #24 Stranded Hook-Up Wire wrapped
tightly and evenly and centered over the Red Wire.

3~6 Inch Ferrite Rod from an old Pocket AM/FM Radio
----------/////////////////////////////---------- Red Wire
----------/--/--/--/--/--/--/--/--/--/----------- Black Wire

Connect the Black Wires : One to the Red 50 Ohm Terminal
and the 'other' to Black [GRN] Terminal.
Connect the Red Wires : One to the 'Long Wire' Antenna
and the 'other' to Ground Wire.

The Plus - Using a Back-of-the-Radio Matching Transformer
with a 'Long Wire' Antenna and Ground usually results in more
consistant Signal Levels across the Shortwave Bands and
reduced Noise Levels too.

The screw labeled RHF is a nut. Get lost Troll.

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.
