Summary

This is an enclosure for the 4SQRP EFHW Experimenter Board. This kit is used to build an Unun for an EFHW antenna. The PCB press fits into the case, and the top holds the PCB in place. m3x6 screws are used to secure the top to the case. I used two insulated binding posts that I had in my parts bin for the EFHW and counterpoise wire connections. However, two small screws could be just as easily used. This is not designed to be permanently mounted outdoors. It is intended to be used for portable operations. -Steve WD4CFN
