9:1 UNUN Kit

This project creates a trifilar wound, 9:1 UNUN (unbalance to unbalance) toroid matching transformer that will match the high input impedance of an end fed antenna into the range where most antenna tuners can produce optimal performance. The matchbox handles up to 100 watts of power.

The 9:1 UNUN Kit from Rocket City 3D includes a UV Resistant ASA printed enclosure, matching transformer, stainless hardware, configuration chart, and instructions. Since you can build the UNUN in many different length configurations, you will need to supply your own long wire. 

SUPER Portable and light! 

Technician Note: This project requires an antenna tuner to achieve satisfactory SWR.
