The MAC-200 is provided with 3 SO-239 connectors, one RF-
Hot/RF-GND pair, and one balanced feed connection. The SO-239
connectors are intended to connect to a normal Coaxial feedline.
Any antenna that is properly setup for Coax feed can be connected
to one of these connectors..
One common benefit of having a
switchable antenna controller is the
ability to leave a dummy load
connected so that you can switch to
it conveniently at need.
The RF Hot/RF GND connections
feed a long or random wire
antenna. They can feed any unbalanced antenna with RF Hot
connected to the radiator and RF GND to the RF Grounding
system.
IMPORTANT NOTE: The RF-Hot connection will radiate RF
from any wire connected to it. Not only is this an RF Hazard
within the station, but it can cause local interference both within
the station and in the vicinity depending on your power level.
The balanced feed connection is for a ladder line feed connecting
to a balanced antenna like a dipole or a loop.
3.3.3 Balanced vs. Unbalanced Antennas
An important distinction is between
balanced and unbalanced antennas.
Balanced antennas are electrically balanced
