Any antenna erected on such a day will inevitably produce miracles. Many of you will recognize THE $4 SPECIAL's design as the venerable "double zepp" aerial, a variation of the "end-fed Zepp" Alas, I never had a 100 foot tower to hang this antenna from.

  • This antenna was modified from my NB6Zep antenna whose plots can be found here. The 88 footer is a simple concept, a dipole fed with open, ladder, or in this case, about 50ft. of TV twin lead (300 ohm). Besides simplicity, one of its virtues is that you get nice twin lobes through 20 meters.

    Apr 29, 2009 · Since the definition of a Zeppelin or Zepp antenna is a Hertz antenna that is end fed with multiples of a quarter-wave balanced feedline ("tuned feedline") and it is described as a multi-band antenna, then, by definition, a Zepp antenna is a multi-band antenna and can be properly called such on frequency bands that are powers of 2 times the ...

    I've long been a fan of parallel-fed doublets or Zepps; in fact, an 80M-length Zepp is my primary low-band antenna at the home QTH. They are multi-band, have very little loss in the feedline and for portable use, the lead is less bulky than coax - and especially with the feed lines used here: zip cord or twinlead.

    Fortunately there is one antenna that can provide effective communication on all, or near all, HF bands: the multiband tuned doublet an tenna—or, as it is often called, the. center-fed Zepp.

    The antenna functions as two full-wave antennas fed in phase; combining the broadside gain of a two-element colinear array with somewhat lower zenith angle radiation than a half-wave dipole due to its long wire characteristic (Fig.8 above). 15 m. On this band the antenna works as a "long wire" of five half-waves, producing a multilobe polar diagram with very effective low zenith angle radiation.

Some of the Topics: Vertical dipole and sloper in free space, over perfect or real ground – sloper with several elements – feeding sloper antennas – multi-band sloper – W3DZZ and double Zepp as a sloper antenna – multi-element sloper antennas for multi-band operation – special types of halfwave sloper antennas and much more!

The W3EDP antenna is a development of the early Zeppelin or Zepp antennas that were used before the Second World War. They obtained their name from the fact that end fed wires were required for use on Zeppelin airships.
