The EF-QUAD - the most popular EndFedz yet! Covers 10, 15, 20, and 40 meters and is rated 200 watts SSB/CW. Need more power? See the EF-ALLBAND-KW, EF-ALLBAND-JR-KW and EF-40-10-KW antennas for more inforamtion
The EF-QUAD may be used as a monobander on any band between 40 meters and 10 meters. This is 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 wrap back along itself for best V.S.W.R.
WB4DBO on the EF-QUAD: “It is a fine antenna and will certainly fill the need for many of us who live in restrictive communities and want a single wire antenna that is simple, easy and effective! Again, congratulations on a great job.”

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.
