Had initial matching unit failure. Steve called me back one hr after I left a message. He told me a test to perform, and it failed. Sent it back and a new unit was provided. New match is now a maximum SWR of 1.3:1 on all bands. Wow! Copied all traffic I could hear on OCF dipole, though 1.5 to 2 S units weaker. Great portable antenna.
Thanks again Steve! Excellent product and customer service.
