1:1 μBalun QRP

A 1:1 "micro" Balun for use on HF (best suited for 7-30MHz) for when you're out portable or need a low-impact balun solution.  Although small, it's light enough to mount on a fishing-pole but still able to operate at up to 100w SSB under most conditions.  As it's a Choke Balun, it can also be used with a Doublet/G5RV at the ladder-line/coax junction and even at the feedpoint of a resonant vertical.

The 2nd picture shows our prototype which had the terminals at the top of the box - along with an Elecraft KX3 for scale.  There is no strain-relief on this Balun, so we suggest using a velcro cable-tie around the BNC connector and your pole - or, loop some cord around the terminals and hang it from a pulley/tree etc.

Perfect for use with small radios such as KX2, KX3, FT817, FT818, IC-705.

• 2x 43-mix cylindrical ferrites with 4-turns of RG316
• Stainless-steel M4 fixings
• BNC connector
• Sealed with potting-compound - fully weather-proof
• 50x35x20mm

For higher power and other options, we also offer a Dipole/Doublet/G5RV Balun/Choke in a 100w version and a 400w version.  If an End-Fed wire is more your thing, check out our End-Fed Coupler.
