I enjoy helping fellow operators get on the air with well-built, handcrafted gear.
My antenna transformers are handmade and tested to ensure each meets the demands of real-world use. I've been a ham for over 30 years and enjoy a wide range of radio activities, especially POTA and digital modes. I build and sell quality 49:1 transformers and accessories to help fellow operators get on the air.

Heading out!
Two more EFHW antenna orders headed into the wild—one to the mountains, one to the coast (or at least that’s what I like to imagine).
Hand-built, tested, and packed with care—because every contact counts.
Thanks to all of you who continue to support small radio makers. You keep the airwaves alive!

After I'm excited about the latest addition to my line of EFHW antennas! After a few request from folks and building upon the success of my original model, I've created a new version featuring a completely different connector system.
My original EFHW antenna, with its compact design and reliable 2mm banana connector, remains a popular choice for many hams.
The new model uses a robust lever-lock connector (similar to the Wago design) that accommodates a wide range of bare wire sizes, from 24 AWG to 14 AWG.
