Palomar MDB-2

The Palomar MDB-2 is a magnetic dipole balun replacing the center insulator. It is for receive only (no transmit!) for 500 kHz to 30 MHz. It converts the balanced signal from the dipole to an unbalanced output for the coaxial cable. It prevents signal pickup on the outside of the coax thus reducing noise pickup. It also connects both sides of the antenna to the coax shield (at DC) so static charges can drain to ground instead of going through the radio. The balun has an SO-239 jack to accept a standard PL-259 connector.
