About Hamuniverse Antenna Design Antenna Safety! THE COAX FED 6 METER EXTENDED DOUBLE ZEPP ZIP CORD ANTENNA (Repeat that title 6 times without stopping!)
W3EDP End-fed Multiband Antenna Charles Lofgren - W6JJZ. Just to remember the old (but still good) antenna tricks, here is a brief description of the W3EDP antenna. The design has lasted through the years. I've explained elsewhere how it is related to an end-fed Zepp (a true Zepp, as once trailed...
The Bobtail fed at the bottom of the middle tail and the next antenna the Double Extended Zepp behave in a very same manner. The gain and the radiation pattern is comparable but if I have to choose I pick the Double Extended Zepp.
These same characteristics also make the "Carolina" windom an excellent receiving antenna. The Original Windom Antenna of The 1930's. The original windom was a Zepp-type antenna fed 14% off-center with a single wire. The single-wire feeder radiated RF all the way into the operating position.
It is a COAX FED 4 to 1 balun attached to a 17 foot long piece of 450 ohm ladder line and a 67 foot long piece of wire attached to one side of the ladder line. This antenna will work with gain and does well horizontal at 10 feet above earth as an NVIS antenna.
The unique COMPACtenna TV antenna is a 3-Dimensional Design and contained within an attractive plastic black box. net The Chameleon HF Multiband Zepp Antenna has been specially designed for apartments, condominiums, homeowners associations, deed restrictions and CCRs (Covenants, Conditions & Restrictions), ARES, RACES, MARS, EMCOMM, NVIS, First Responders, Emergency Preparedness and attic antenna installation.
