HF Impedance Transformer Kits

BULLET Impedance Transformers (1:1, > 1:1)

Store/Antenna Products/BULLET Impedance Transformers (1:1, > 1:1)

BULLET format transformers are made in ratios from 1:1 up to 16:1 in 100/500/1500/5000 watt PEP Models. We also make BULLET Hybrids of NN:! + 1:1 in the same enclosure.

These impedance transformer kits have been designed for the Do-It-Yourself (DIY) enthusiast and Instructor workshops on baluns and ununs for antenna matching and RFI use.

The impedance transformers are classified in ratios of 2:1 (100:50 ohm) to 16:1 (800:50 ohm).  The outputs can be configured as balanced (Balun) or as unbalanced (unun) with respect to the inputs which are considered all unbalanced coax at 50 ohms.  All impedance transformers are designed for 1.8-31 MHz unless otherwise specified.
