3.2 User Supplied Items
The user of the SG-231 will need to supply a suitable HF radio antenna. Such an
antenna may be as simple as an 8-foot-long piece of wire and several ground/
counterpoise radials of 8 feet or longer. The longer the antenna, up to about 80 feet, the
better all around performance will be. Longer antennas may be used, but please refer to
the sections on antennas for discussion of limitations.
The user will also have to supply a good counterpoise. Such a counterpoise is a large
metal surface (much larger electrically than the antenna). Generally, the bigger the
counterpoise, the better your signal will be.
3.3 Technical Support
Before contacting SGC for technical support, please take a few minutes to think through
your installation and ask if there is anything obvious that 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-231 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.
