The MFJ-4113TR has an on/off SWITCH to switch between transmit and receive for different T/R antennas. VSWR <1.5:1 below 150 MHz and 1.16:1 below 230 MHz.
The MFJ-4113TR allows you to power an active antenna with an in-antenna amplifier;
power a remote tuner on one port and switch to another antenna on the other port;
switch between a receive antenna such as the low-noise MFJ-1886 and a transmit antenna (beam or vertical).
Power to the DC-Pass port is grounded through a 100 Ohm resistor.
