The good thing about base-station and two-way radios is that they allow
you to extend range by using an external
. The base station units have what's called a BNC
connector that enables you to twist off the antenna that comes with the
radio and then twist on a new antenna connected to a cable.
You will get noticeably better results and more range with your
radios with an external antenna, especially if you can place it high. It
is the single most important factor in increasing transmitting and
receiving range of a radio. You'll need to make sure you choose an
antenna that is specifically designed for the frequencies and
application you are using and then choose the best location possible to
For MURS radios, the FCC limits antenna height to 20 feet above a
structure (exclusive of the tower, mast or pole on which it is mounted),
or 60 feet above ground (whichever is greater). The higher you place
your antenna, the greater range you will get. If you mount an antenna on
your vehicle and connect it to your mobile MURS two-way radio, the
higher you place the antenna on your vehicle, the greater range you'll
If you are using a handheld radio and walking around with it, you
can't very well use an external antenna. You may be able to extend range
by installing a better antenna than the one that came with the radio,
but keep in mind that the antenna that came with the radio is "tuned"
specifically for that radio. If you put on an antenna that isn't
properly tuned, you could lower range.
