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

These RFI kits are specifically selected to cure most household computer device RFI problems. It contains ferrite toroids for AC or DC power supply protection and Snap On ferrite spli beads selected to eliminate RFI from 1 to 1000 Mhz. The beads are easy to use, don’t require modification of the protected equipment and work in almost all cases, even when plug-in filters fail.

Typical Installations
