3.3.5.6 Loops
Loop antennas are balanced antennas that are very simple to feed
from a balanced feed line. Ideally, a Smartuner would be at the
loop feed point, but when using the MAC-200, balanced feedline
will minimize SWR between the MAC-200 and the loop. A loop
would typically be connected to the MAC-200 at the BALANCED
connection (switch position 1).
Loops can be
conveniently arranged
either horizontally or
vertically, but the
feeding arrangement
from the MAC-200
would be the same.
Loops can take on nearly
any closed shape such as a
square, rectangle, triangle,
or diamond shape and they
can be fed on the sides or
in the corners. The impact
of different configurations
and feed points is well
documented in the many
books on antennas.
It is also possible to feed a loop from a Coax connection by
connecting one side of the feed point to the center conductor and
the other side of the feed point to the coax shield.
