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.
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.
