Manual Antenna Switches
MFJ antenna switches have
precision-machined, low loss
components for reliable service. Mount
one of these antenna switches and you will
have more than the convenience of instantly
selecting any of four antennas or center ground
positions. They come complete with replaceable lightning
surge protection that helps to protect against distant
lightning-induced surges and static. When these antenna
switches are in the center position, all connectors are
disconnected and grounded. If the switch is turned to an
active connector, the other connectors are automatically
grounded. The active connector is automatically protected
with the replaceable lightning/surge protector. MFJ antenna
switches utilize heavy cast metal construction and a ball
bearing drive for smooth switching.
Additional features include:
• Handles 2.5 kW PEP
• Extremely low SWR
• Isolation: greater than 60 dB at 30 MHz, greater than 50 dB at 500 MHz
• Negligible insertion loss
• 50 Ω Impedance

covers 1 to 60 MHz (lowest SWR from 1 to 30
MHz), and is made for 50 Ω antenna systems.
All unused ports are grounded automatically
and the switch features an ultra-fast gas tube
lightning surge protector to protect your radio.
This switch is remotely operated through an RJ-45
cable by the MFJ-4724RC remote (sold separately).
