Yes, I looked at the Array Solutions units, but boy, do they think a lot of
them ! The TXBPF was a way to get building experience with SMD's and really get
in the weeds on what these units actually do and how to measure it. It was a
great ham radio experience - and they work very well. Plus I saved many dollars
! :)
