three SO-239 connectors on the MAC-200 (switches 3, 4, or 5).
Any vertical antenna fed with Coaxial cable can be connected in
this way.
Home made vertical antennas
are commonly made in one of
two ways. A very common
type of construction builds the
radial system at the base of the
antenna. Flag pole antennas are
normally built in this way.
Coax line can be run from the
MAC-200 to the base of the
antenna. The center lead of the
coax will feed the radiating
element in the flagpole vertical while the coax shield will be
connected to the RF grounding system.
Another way that a vertical can be fed is to have it fed with a wire
directly from the MAC-200 with the RF grounding system also
connected directly to the MAC-200. In this case, the vertical will
be connected exactly like a long wire antenna to the LONGWIRE
lugs with the vertical element connected to the top lug and the RF
Grounding system connected to the RF GND connector. This
configuration could be a very poor radiator unless the feed line is
elevated from the ground. The feed wire in this case will be part of
the RF radiating system.
