About this product

Dudetenna Lite EFHW Kit. Available in SO239 and BNC.

with 100 ft of included wire, you will be able to cut the efhw for 40m and get 4 bands, 40, 20, 15 and 10m. some of the extra wire can be used for a counterpoise.

This End Fed Half Wave Kit is made for a budget and includes the following:

  • One high Quality ASA Wire winder available in BNC or SO239. ASA is one of the optimal 3D printed materials. (By default, SO239 is selected. Please select the BNC Variation if you need BNC)
  • 100 Feet of BNtechGo, 22awg Silicone Wire. The color is black.
  • Appx 5.5 Feet - of 18 Gauge Magnet Wire . This should leave you plenty of extra magnet wire.

1 - 100pf / 3kv capacitor
1 - SO239 Connector (or BNC)
1 - T140-43 Toroid. This is the typical toroid found in most entry level EFHW kits now.
1 - 1"x8" Cinch Elastic Cable to hold wire
3 - zip ties
2 set of Stainless Steel Hardware (#8 size)
4 Ring connectors.
1. Dude Coil (this is a resonance coil that probably will not be needed but could help tame 20-10m.) If you want to experiment, Wrap this 10-12 turns, approximately 6ft from the toroid (on the Antenna wire).

I prefer a 49:1 winding with a crossover at turn 8. This is ham radio, feel free to experiment.

Note: This EFHW kit is made for portable use and not intended to be permanently mounted outdoors.

Shipping is on you. This means if you choose First Class (Ground advantage) mail, USPS may delay the delivery by shipping it to many different locations in the US. I've had packages going to the east coast but also stopping in California. I tell you this, because I cannot control USPS' route. If you want faster shipping, please select Priority mail.

Instructions for the Dudetenna Original (With the big toroid) can be followed:
youtu.be/Y-ojVTQbszw and youtu.be/VvYtT-4UwqM
or
Build Instructions for the Dudetenna original are now available (and can be followed) at hamradiodude.com/documents/Build_Instructi… (Build instructions may be slightly different than the build video due to changing parts / upgrades during the process between the video and Instructions)

___________________

As of 05/25/2024, each kit now comes with two Stainless steel screws, nuts, and wingnuts and a total of 4 ring connectors. This gives you the option of having both your antenna and counterpoise wire connected to posts.

Good gear. Love that the PVC pipe was included with the spike kit. I already had a spike I purchased earlier, it's so useful I had to order a second one.

I was happy to see the high quality components that were thoughtfully engineered. I set my EFHW up for coverage 10m - 40m with dedicated 1/2 wave breaks for 10m, 17m, and 30m as well.
