This QRP balun is the newest in our low power offerings and provides over 30db of suppression across the full HF spectrum of frequencies. Our design provides high levels of feedline isolation, RF choking and excellent return loss for those who...

We're bring back one of Dr. Jerry Sevick's (W2FMI) original designs but with upgraded windings.  This balun was one of our original workhorses and now with new coaxial windings, provides a single core balun optimized for 40 -10m.  By using our...

After much research and testing, a new transformer design for End Fed Half Wave (EFHW) antennas has been achieved. Developed by Bob Glorioso, W1lS and Bob Rose KC1DSQ, they discovered that most transformers for EFHW antennas used higher impedance...

For those that enjoy half wave end fed antennas but want to run more power, Balun Designs now offers an excellent alternative.  Built with the same craftsmanship as all our other units, this new model will allow you to either replace your current...

While primarily designed for use with a "Loop on Ground" antenna, this is an excellent 9:1 isolation balun for any receive application.  Separate input and output windings provide a high level of isolation and noise reduction and to maximize...
