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.

----------/////////////////////////////---------- 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.
