With the LDG tuner, you can use a banana plug ( »www.digikey.com/product-detail/e ··· ND/35146
) in the center of the SO-239 connector and a hose clamp warped in tape (except ware the counter poise wires attach) on the out side of the connector.
Run a long wire of about 40 to 60' and 3 to 4 counterpoise wires about 30' long.
If you want to go a little more sophisticated, do a web search on how to make a 4:1 UnUn. For long wires and vertical antennas, you want to use a UnUn (Unbalanced to Unbalanced)and not BalUn (Balanced to Unbalanced), since these types of antennas are unbalanced unlike dipoles and beams.
You can also buy one from LDG or balun designs if you do not want to make one.
