End-Fed Horizontal Wires(EFHW) cover multiple bands with-out traps, stubs, or resonators.
End-fed radiators have the unique quality of resonating on the 1/2-wave fundamental frequency plus odd/even harmonics above!
Broad-band matching transformer at feed point lets the entire HF spectrum be yours! SWR is so low you may never need a tuner.
Get on the air! Just one high center or end support -- installation is fast for home, road, emergencies.
EFHWs install virtually any-where in minutes! Comes with a rugged insulated-wire radiator that prevents detuning when contacting limbs/branches. \"No-snag\" end insulator slides over branches and through foliage without hang-ups.
Toss your EFHW over a high limb for an inverted-V, raise the far end high for a powerful sloper, or even go vertical with an inverted-L. Dark jacketed wire is virtually invis-ible -- Don`t let antenna restric- tions keep you off the air!
It`s no secret that weather events are getting stronger -- the EFHW makes a great emergency back-up for your regular antenna.
Power ratings are in Watts PEP for SSB/CW modes, with 50% or less transmit time (ICAS). Each network designed and tested to ensure great performance in a wide range of operating conditions.
End-fed horizontal wire, an EFHW, offers the perfect solution for a wide range of ham activities.
Whether you`re QRPbackpack, vacationing, emcomm station, or an antenna neighbors will never see, MFJs got an EFHW for you
