Long time QRPer.com contributor and supporter, Jonathan (KM4CFT) has designed and started producing ultra-compact end-fed antenna kits.
His end-fed antennas are incredibly small, thus perfect for portable operations. They remind me very much of K6ARK’s end-fed wire antenna kits, but a little easier to build because the board is larger and there are no surface mount components.
Jonathan sent me one of his end-fed kits (assembled) a couple weeks ago, but I’ve yet to trim mine due to my crazy schedule and activities as of late (well, that I need need to order more wire!). I will take this antenna to the field this month, but the video may not show up for a few weeks.
W2AEW Builds the KM4CFT UNUN
This morning, I learned that my good friend Alan (W2AEW) published a video where he builds, tunes and tests Jonathan’s QRP End Fed UNUN kit:

Alan’s video is superb. If you purchase this EFHW kit, I’d encourage you to watch his build. (And subscribe to his channel!)
How to purchase
Jonathan is selling his antenna kits on eBay–click here to check it out. The price is $29.95 plus a modest shipping fee. I think it’s an excellent deal.
Of course, you’ll need some wire for your radiator and/or counterpoise.
I plan to build mine with a 30 meter link to pair with my Mountain Topper MTR-5B.
