More than any other
factor, a good RF
ground will help to
improve the radiated
signal from these
antennas and minimize
RFI generated by the
antenna.
As a minimum, an RF
Ground can consist of a
wire 5-10% longer than
the wire antenna and
laid out so that it does
not cross over itself or form a loop. A far better RF ground can be
constructed by adding ground radials connected to the RF GND
lug on connector 2 of the MAC-200.
3.3.5.5 Vertical Antennas
A vertical antenna may be
connected to the MAC-200
in a number of ways. Most
vertical antennas will require
an RF Ground system to
function properly, but this
may be incorporated into the
design of the antenna itself.
A typical vertical antenna is the GROUND PLANE design that
incorporates radials within the design. This, and many other
vertical antennas use an SO-239 connector or equivalent to feed
