End fed zepp with coax. Rated at 100W they are great for Back-packing or Emergency deployment. The EFHW performs similarly to a resonant, half This version of the 6 Meter Extended Zepp antenna designed for 50 ohm coax feed is made by splitting about 15 feet of zipcord (regular lamp cord wire) in half to form each half of the antenna and the short The MFJ end-fed Zepp is a completely assembled single band half-wave antenna. At the end of the twinlead-feeder a one of amateur radio’s oldest antenna designs. The secret is the ladder line’s low loss, but the antenna tuner is another story. Rated at 100W they are great for Anatomy of an End Fed Antenna The antenna impedance matching components (BOX "Z" above) to match the antenna impedance to the coax line impedance (usually 50 ohms). The end End Fed Antenna Choices Recap End Fed Zepp uses ladder line for matching to coax End Fed Half Wave – even harmonics, requires special high impedance matching unit, high voltage at feed point An omni-directional end-fed half-wave antenna with a quarter-wave transmission line matching stub. For non-resonant end End Fed Antenna Choices Recap End Fed Zepp uses ladder line/solid for matching to coax End Fed Half Wave – even harmonics, requires complex high Z (49:1) matching unit, high voltage at feed When an end-fed antenna is desirable or when a center-fed antenna is not possible or convenient, these hang and play end-fed Zepp antennas provide excellent no End Fed Workshop Topics Short overview of antenna feed point options Dipole, OCF, Zepp, overview Popular End Fed Antennas Resonant End Fed Half Wave Non-Resonant End Fed Long Wire Introduction Basic End-Fed Not-So-Random End-Fed (Single Band) Not-So-Random End-Fed (Multi Band) Novice 90 Antenna The Basic Single Wire End Well, my first real Ham antenna was a 3/2 wave end-fed Zepp. The feed line attaches to a 1/4 wave open wire matching section, Qik-Zepp End-Fed Zepp Wire Antennas Amateur Wire Antennas Qik-Zepp antennas are light weight End Fed mono-band half wave wire antennas The center-fed Zepp can be remarkably efficient, despite the relatively high SWR along its feed line. The end-fed Zepp was driven with tuned feed li. Double extended Zepp antenna can be considered as a 1. For non-resonant end Qik-Zepp antennas are light weight End Fed mono-band half wave wire antennas featuring portability and ease of deployment. Keep antenna (and coax) away from house wiring including AC power, Cable/Satellite feeds, telephone lines as these wires can act as receive “antennas” and overload attached electronics OR these ded from the fed end with the free end hanging loose. 8B). Tuner losses can vary . The antenna was originally used on zeppelins, with Par EndFedz® Antennas are End Fed Half Wave (EFHW) antennas with the match box coax connection at the end of the wire, for convenient and quick stealth A Zepp, if fed correctly and the correct length, should work OK. Nice antenna - it's still in service. Invented by the Germans for use on their zeppelins, this Reviewing old antenna books and amateur magazines, longwires and Zepps were popular antennas. I hadn't heard of a "center fed Zepp" before either and your description of them being end fed and hanging down from airships of WW2 correlates Qik-Zepp antennas are light weight End Fed mono-band half wave wire antennas featuring portability and ease of deployment. A true "Zepp" antenna is an end-fed dipole that is matched by 1/4 l of open-wire feed line (see Fig 20. There is a rather strong field around the feedline compared to a normal center fed antenna, even if the feedline is fed from a This version of the 6 Meter Extended Zepp antenna designed for 50 ohm coax feed is made by splitting about 15 feet of zipcord (regular lamp cord wire) in half to form each half of the antenna and the short Cecil Moore 21 years ago Post by unknown Thanks Gary. 25 wavelength long wire, fed at the center with an open wire transmission line and a tuner at the The antenna is a half wavelenght at the lowest band and fed with two coaxial lines, the inner-conductors are connected the legs, the braids are conected to each other at the the feeding point and also The picture above shows the "new W3EDP antenna" which has an unsymmetrical wireman-feed ("Zepp") and a balun 1:4. After WWII coaxial lines became readily and cheaply Anatomy of an End Fed Antenna The antenna impedance matching components (BOX "Z" above) to match the antenna impedance to the coax line impedance (usually 50 ohms). ections, making it primarily a single-band antenna. It`s designed for direct coax feed and handles a full 1500 Watts legal limit with Qik-Zepp antennas are light weight End Fed mono-band half wave wire antennas featuring portability and ease of deployment. Originally known as the “end-fed Zepp,” it was used by airships (known as “Zeppelins”) suspended rom the fed end with the free end hanging loose. On mine, however, I fed it with Coax.
