The AOR MC-600 addresses answers the question, How do I hook up my 50 ohm antenna to my antique receiver that only has high impedance screw terminals?
Many classic receivers from the Golden Age such as Hallicrafters, Hammarlund, National and Eddystone do not feature a 50 ohm coax input jack. The MC-600 allows an efficient connection of your coax fed antenna to these receivers. This impedance matching transformer is designed to work from 10 kHz to 30 MHz with less than 3 dB insertion loss. No power is required. Input is 50 ohm BNC female. Output is 600 ohm balanced terminals. A short twin-lead jumper cable is supplied. For receive only.
