About Us

Back in the mid 70’s CB radio was all the craze, for me it wasn’t just a hobby it was an obsession! Always on a quest to improve the quality of my radio’s distinct clear clean sound. Soon my passion for CB was getting notice and people started bringing their radio equipment for me to duplicate that big clear sound, it didn’t take long and business really blossomed.

In 1995 Circuit Master CB moved into Bosselmans new Travel Center (Now Flying J ) located on Interstate 80 exit 142 in Altoona, Iowa. Our new location allowed us to expand into serving the trucking industry as well as state wide farming operations.

Our goal was simple, Be Honest, Give Great Service at a Good Price and Treat People Right !

20 years later Circuit Master CB is still here providing outstanding service, sales and customer support. Our dedication to excellence, a job done right warranty and  always putting “You” our customer first has and always will be our greatest privilege .

Today Circuit Master CB offers everything from professional custom installations on Semi Trucks and Farm Machinery to Cars, Pickup Trucks, RV’s, Motor Cycles and Boats. We also offer a full line of Cobra, Uniden, Connex, Galaxy, Ranger and General Radio’s as well as all the popular antennas and microphones.
