The Drake MN-4 matching network handled transmitter outputs of up to 200 watts. It matched unbalanced loads up to 5:1 VSWR and had band-switched coverage of 80–10 meters. The MN-4 had a switch position for an external dummy load and another that bypassed the tuner.
Appears to have been replaced with the MN-4C in September of in 1978. See separate listing for MN-4C.
