1:1 μBalun 100w

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 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.

All fixings are stainless-steel and we now include a pair of wing-nuts if you prefer "quick-release" Hamming.

2nd picture shows our prototype with the terminals at the top of the box and an Elecraft KX3 for scale - yes, the box is small!

• 2x 43-mix cylindrical ferrites with 4-turns of RG316
• 2x M4 bolts for aerial wires
• Wing-nuts now included for optional quick-release use
• BNC connector
• 50x35x18mm
• Weight: 50g

We also offer a standard 100w Choke/Dipole Balun, plus a 400w Doublet/G5RV Choke.
