Description: Today's video features the ARRL EFHW Antenna Kit by HFKits.com, which is essentially a nice, weatherized 49:1 UNUN Transformer to convert the 2500-3000 ohm end-fed halfwave feedpoint impedance down to approximately 50 ohms. I review how to build/assemble the unit, and run a quick bench test. The kit is available from the ARRL as well as HFKits.
