Available as a Unun for 50 ohm coax to 75 ohm coax or 75 unbalanced load or as a Balun for 50 ohm coax to balanced load such as a low (less than a wavelength high) dipole with either side eye bolts and halyard hoist or as post mountable top studs output.

This is an impedance transformer for 50 to 75 ohms and may require a additional feed line choke to keep common mode current off the coax braid.

CB-1.5-1500EB is useful for a dipole center feedpoint for low dipoles with 75 ohm antenna impedance.

Top stud version also useful for 75 ohm ladder line to coax interface

The high power ferrite impedance transformer series (> 1:1), configured with outputs to act as a baluns (unbalanced coax in to balanced load output) or as ununs (unbalanced coax input to unbalanced load output) are designed for demanding radio transmitter stations that run over 1,000 watts PEP or run continuous modes like AM, digital, RTTY, FM, etc. at high power levels. Radio contest operators, commercial shortwave broadcast, and industrial and commercial stations use these transformers for for a variety of balanced and unbalanced antenna loads. Baluns are typically used for balanced loads and antennas like dipoles, loops, log periodics, and direct feed yagi/beams. Ununs are used with verticals, end fed wires, horizontal dipoles, G5RV/ZS6BKW, Zepps, vertical wire beams, etc). All products are in an enclosed NEMA water resistant box with SO-239 input connector and stainless steel side/top studs with wing nuts or side and top eyebolts. The enclosure box has mounting “side feet” for attachment to a post or antenna boom using nylon ties.
