High-Power EFHW is HERE!

You asked for it, and here it is. Our newest release is a higher-power version of the End-Fed Half-Wave (EFHW) antenna. Same small size, same simple setup, just with a little more muscle. Get it now on our RadioPrep Etsy store.

This one is rated for 80 watts SSB or 40 watts CW/Digital, which means you can push a bit more power through it whether you’re chasing DX from the park or checking in on your favorite net. It’s only slightly bigger than our QRP model, but don’t let the size fool you—this little box is ready to play.

The Lever-Lock Difference

Here’s the part I’m most excited about: with so much positive feedback, we went with a lever-lock system for this one. Just strip the insulation off your wire, drop it in, close the lever, and you’re done. That’s it. No soldering, no banana plugs, no “where did I put that adapter?” moments.

If you grab one of our pre-cut wires, be sure to choose the BARE option. (The 2mm banana won’t fit the lever-lock, and you’ll miss out on how easy this is!)

Why You’ll Like It

• Quick setup – connect almost any size bare wire in seconds.

• Works the bands – from 80 through 10 meters, just choose the wire length that fits your style.

• Strong on the lows – built with 43 material, it really shines on the lower bands.

• Packs small – toss it in your bag, it’s weather-resistant and field ready.

• Built by hand in Texas – every unit is assembled and tested right here.

The Details

• BNC female coax connector

• Weather-resistant semi-rigid cover

• Comes with an S-carabiner (color will vary—surprise!)

This antenna is all about keeping things simple without giving up performance. If you liked the original QRP version, you’ll love this one. More power, same small package, still easy to carry anywhere.

Wire Length Cheat Sheet

Want multi-band? Go long. Want a single band? Go short. Here’s what works:

Length	Band(s)
134 ft	80m–20m–15m–10m
67 ft	20m–15m–10m
43 ft	30m
33 ft	20m
22 ft	15m
16 ft	10m

(As always, trim for lowest SWR.)

Thanks to Thomas at QRPer!

A big thanks to Thomas over at QRPer.com for taking the time to put my little EFHW through its paces!

There’s nothing quite like sending an antenna out into the wild and then getting to see it tested in real-world POTA conditions. I can tinker, test, and trim all day in the backyard, but watching someone else deploy it, work stations, and share their honest impressions is priceless.

I really appreciate Thomas not just for the thoughtful review, but for the work he puts into documenting his adventures. If you’re not already following QRPer, you’re missing out on one of the best blends of radio, gear, and field fun out there.

Thomas, thanks again for giving the RadioPrep EFHW some airtime. Operators like you make this hobby so much more fun and inspiring.

Now back to the workbench, because there are always more wires to cut, trim, and tangle. 😅
