The user of the SG-235 will need to supply a suitable HF radio antenna. Such
an antenna may be as simple as an 23 foot long piece of wire and several
ground/counterpoise radials of 23 feet or longer. The longer the antenna,
up to about 300 feet, the better all around performance will be. Longer
antennas may be used, but please refer to sections on antennas limitations.
The user will also have to supply a good counterpoise. Such a counterpoise is
a l a r g e m e t a l s u r f a c e ( m u c h l a r g e r e l e c t r i c a l l y t h a n t h e a n t e n n a ) .
Generally, the bigger the counterpoise, the better your signal will be.

Before contacting SGC for technical support, please take a few minutes to
think through your installation and ask if there is anything obvious which
you have overlooked in the installation. Check to make sure your ground
system is both adequate and tight and that proper voltage is supplied to the
coupler.
In the event you experience difficulty with your SG-235 antenna coupler,
you should contact SGC for technical advise. Before calling, we ask you to
have the following information ready so that we may readily assist you.
