About us

DXpander is a small business based in Central Florida, dedicated to innovation in antennas and radiocommunication solutions.

The company was founded by Erwin Hübsch Neto, amateur radio operator W4HUB in the United States and PY2QI in Brazil.

Licensed in Brazil in 1980 and in the United States since 2012, Erwin brings decades of experience to the amateur radio community. 

Born in Southern Brazil — a region strongly influenced by European immigration — he carries a proud German heritage. Currently living in Central Florida, you may have met him at major amateur radio events like the legendary Dayton Hamvention® or while he was exhibiting Cobwebs antennas at Orlando HamCation.

His passion for radio communication bridges continents, combining technical expertise, tradition, and innovation.
