We sent an RFC-101 to Michael, KB9VBR, who was kind enough to give an overview of the product on his YouTube channel (link here).
His earlier post on the POTA Performer antenna was actually the impetus for us to develop the RFC-101. We were excited to try out the antenna from that video and get into Parks On The Air, but after finding the MFJ-915 no longer available, we decided to make one ourselves.
And without using sewer tubing while we were at it.
Thus the RFC-101 was created, Propagation followed shortly after, and we have a few other ideas in the works.
Thanks again Michael!
