RADIO WORKS - B4-2KX - 4:1 CURRENT BALUN - 2 kW p.e.p Max. - 50 ohm impedance - 160-10 meters (1.6 - 30 MHz) 

Exceptional 4: 1, CURRENT type BALUN, able to withstand 2000W p.e.p. from 10 to 160 meters.

The B4-2KX is inimitable, employs 2 large toroids and can be used both for dipoles and directives.

Its exceptional structure makes it an even better replacement balun than the original for KLM KT-34A and KT-34XA type antennas.

This is the INCREASED version of the B4-2K, identical in size but internally to a double toroidal core.

Indeed
X = Indicates the Balun made with Double Core, X-coupled 

The Baluns produced by Radio Works are real CURRENT type.

Construction type: HEAVY-DUTY, with eye bolts in STAINLESS STEEL, not connected internally. This reduces the noise in the receiver resulting from the connection of dissimilar metals.

They are able to withstand HIGH VOLTAGES, HIGH TEMPERATURES in conductors, and have huge toroids with unmatched characteristics. Excellent waterproofing treatment.

The conductors coming from the internal windings are brought directly outside the container for connection to the antenna terminals, thus without the possibility of interruptions or cold welds.
