■ Standard usage method

How to take the ground

If the ground is incomplete, it may not be able to wrap or tune, or the SWR may increase during operation. Be sure to take the ground. Please refer to the installation example for how to take the ground.

● Exampale of Ground Installation

In addition to installing it on the ground with a ground rod, you can use an iron veranda (installed on the ground) or a metal water pipe (no gas pipe).

● Counterpoise

If it is not possible to install it on the ground, prepare several wires longer than the antenna, connect them to the GND terminal, and stretch them radially into the ground.
