USES FOR THE MFJ-204B ANTENNA BRIDGE
Your MFJ-204B ANTENNA BRIDGE has many uses. It can be used to find the
resonant frequency of your antenna, to find the SWR of your antenna at a particular
frequency, and to find the frequency at which your antenna has the lowest SWR. You
can also use the Antenna Bridge to adjust your antenna to a low SWR and to adjust an
antenna tuner to match the transmitter to your transmission line. You can even find out if
your antenna is resonant on more that one frequency.
The added benefit of using an Antenna Bridge over a SWR meter is that you can adjust
antennas to impedances other than 50 Ohms. This is handy if you are using CATV
hardline, Ladder line or any other non 50 ohm coax.
