Desktop/Remote Six-Position Antenna Switch
INTRODUCTION
The
MFJ-4716
is a versatile multiple antenna switch designed to switch up to six
50-ohm antenna systems. It handles high power, up to 1500 Watts and sealed
relays offer excellent life and connection reliability. The unit is operational from
1-60 MHz and useable to 150 MHz. See Table 1 for the best antenna connection
for your particular frequency.
The MFJ-4716 Desktop/Remote Antenna Switch uses a simple rotary switch to
select one-of-six antennas and connects those ports directly to a single common
port for a feedline. Use the MFJ-4716 Desktop/Remote Antenna Switch on your
desk or place it out-of-way under your desk or in another room and use a remote
control. In the OFF/Remote position, all inputs are grounded or control is
transferred to the MFJ-4716RC Remote Control. All unused inputs are grounded.
You can connect a sense line to your transceiver so when it’s off all inputs are
automatically grounded.
The MFJ-4716 will work well in nearly any system requiring switching of coaxial
lines, especially those requiring good quality 50-ohm RF switches. Any switch
port can be used as either an input or output, so you can select one-of-six radios
to one feedline or one-of-six antennas to a radio.
