  • This antenna is two λ/4 verticals, spaced λ/2, fed in-phase by the top wire. The cur-rent maximums are at the top corners. The theoretical gain over a single vertical, for two in-phase verticals, is 3.8 dBi. 10 An im-portant advantage of this antenna is that it does not require the extensive ground sys-tem and feed arrangements that a conven-

  • Oct 06, 2019 · That is the saving grace which helps antenna designers to often include the 15m too in a multi-band antenna design but not always. However, making a multi-band resonant wire antenna for covering all other bands minus 15m is quite trivial thanks to the nature of amateur radio band allocation.

  • Jul 21, 2018 · The sloping dipole antenna (fig. 3) offers directivity in the direction of the sloping antenna. Note that the dipole element pointing up should be connected to the center conductor of the coaxial cable. This antenna is for vertical polarization via ground wave and long-haul ionospheric propagation, and requires just one point of suspension.
  • If the transformer is used with an external tuner in conjunction with a single wire antenna typically 130-135 feet in length, power should be reduced on those bands that show an SWR above 1.6 to 2:5 without the tuner. A level of 500-600 watts is the maximum with a further reduction on any band measuring above 3:1.

  • Originally these antennas were called "half wavelength Hertz Aerials" and were fed with a single wire. Later they were fed with two wires (which I generically call openwire) and called a Double-Zepp Aerial (or Antenna) because they could be viewed as being two single-wire Zeppelin antennas, fed with a common balanced feedline.
