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.”
