Beams
Typically, the radiating element of a beam is a dipole antenna fed
with coaxial cable. Connecting a beam to the MAC-200 is
accomplished by connecting the coax to positions 3, 4, or 5.
3.3.6 Tips & Tricks
1. The most frequent source of problems in unbalanced
antenna systems is the RF Ground. RF grounding is
frequently misunderstood and poorly implemented. See
our book The HF User’s Guide available free for
download from
http://www.sgcworld.com/ftp/Books/hfguide.pdf
2. Be aware of the difference between a SAFETY ground
and an RF ground. Safety grounding is necessary to
protect your life and property from coming into contact
with lethal doses of electricity. RF grounds, when
required, are necessary to the operation of your antenna
system. Connecting the two together can inject RF into
your other electronic equipment.
3. It is a good idea to reserve one SO-239 position on the
MAC-200 for a dummy load suitable for initial tune-up
on your transceiver.
4. Plan your antenna installation carefully!
5. Don’t commit to a final installation until you have tried
out your antennas in as near to final form as possible.
