Clone of PAR End Fed Antenna Matching Network

A clone of the PAR EF-20 end fed antenna matchbox under construction at the W0QL radio ranch.  This kit is a prototype from the Colorado QRP Club which the club is thinking about selling.  It would be a fundraising project for the club.

What we’re doing here is building from a kit of parts to make a matching network that emulates the matching network that comes with the EF-20. The kit consists of a toroid and three pieces of wire, plus the box and hardware. We don’t really know what’s in the EF-20 matchbox because it’s sealed in epoxy.  It’s potted and we can’t see the components without ruining it.  I’ll post some results once I have it up and working.
