EF-10/20/40 MK II EndFedz® Antenna w/SO-239 connector.
The original multi-band QRP (25 watts) EndFedz®. The Mark II version of the earlier EF-10/20/40 offers an inline choke which helps preventing it from being snagged in the trees when putting it up through branches or brush.

The EF-10/20/40 may also be used on 20/30M by replacing the 40M tip with a 38” tip. This will raise 20 meter resonance a bit, but should not be a problem especially if 20 meters was initially set to the CW portion of the band or by connecting the stub to the choke end closest to the matchbox and reestablishing 20 meter resonance as desired. Alternatively, for 30 meter monoband use a 1/2 wavelength wire– begin with 46.5’ of wire.
Operation as a monobander on any band between 60 meters and 10 meters can be accomplished by removing the factory radiator and installing the appropriate 1/2 wavelength wire. Calculate the approximate length from L= 468/F(MHz). As an example a 25’ 10” wire will allow operation on 17 meters as a monobander. Initially, cut the wire a bit long and trim or fold back against itself for best V.S.W.R.

When I received my call sign a few years back, I was flooded with purchases of junk. Fast forward to 2019. I decided I wanted to build another option, not a dealer who has the same stuff as everyone else, but a dealer who actually uses what he sells. And that’s exactly what I do. If you see a product on this page or one of our tables at Hamfest, you can bet we have tried it and like it. From Radios to connectors we strive to bring you QUALITY. Sure, you can find it cheaper and we understand that, but if you don’t want to buy it again in 6 months, take a look at what we sell and have already approved. I am always just a phone call away.
