Description
Specifications
 

Heavy duty 5kW, 4:1 unun designed for use with wire verticals, long wires and monopole verticals. Utilizes stacked cores to deliver efficient broadband performance and high power rating across all HF frequencies. Works well with both internal transceiver and external antenna tuners.  The model 4134u is designed primarily for the Eagle One multiband vertical but can be used anywhere two SO-239 connectors are desired.

This unun is an excellent match for any of the 43 and 31-33 foot multiband verticals including the S9, ZeroFive, MFJ, Eagle One  and DX Engineering vertical antennas allowing the use of full legal limit ++ power. When used with smaller diameter wire vertical, performance will be slightly less than that of larger diameter aluminum or copper tube/pipe.

NOTE: For ground mounted vertical installations, the "s" model (4134s) is strongly recommended. 

Although many customers report very good performance using just a single ground rod, the best performance will come from using at least 4+ ground radials or several elevated radials. In a temporary or emergency situation, a single counterpoise can be used when cut to approximately 1/4 wavelength of the lowest operating frequency.
