DG7YBN - 144 MHz YU0B Beam With the K8AT skeleton slot driven double boom Yagi as a starting point. As the K8AT antenna showed a novelty, whichThe following is only valid and of use for the particular '11+11' original YU0B antenna. The '11+11' means 10 parasitc elements per boom plus 1 each as horizontal part for the slot. Slot Antennas | Antenna (Radio) | Capacitor All slotted-cylinder antennas seem to be called an “Alford slot” by hams, but the name is not used in any antenna book I’ve seen.A properly dimensioned Alford slot antenna will produce a clean elevation pattern with a single lobe, like the one in Figure 7-39, measured by KB 2BD39 for a skeleton...

He said it was based on the >discone antenna design, but only used 2 or 3 descending "elements" ... There was an article in 73 by W5ZCC about the skeleton slot antenna The D2T AAntenna compared it with my skeleton slot antenna, which is an elongated loop, as described in The Antenna Experimenter’s Guide (1). The skeleton slot antenna has a calculated gain of 11.5 dbi on 28 MHz ( including ground reflected gain, and as installed at my location ). The D2T was 1 to 1.5 S-points down on the skeleton slot on 28 MHz. 2 METER HENTENNA - Hamuniverse 2 meter version of the Hentenna. (The following has been edited from emails from Terry in the order of his progress) "I thought I'd drop a note about my experiences with the Hentenna. I just built a 2 Meter version of it out of 1/2" copper pipe. It was 39" x 13", a nice workable size for a gain antenna.

THE (VHF) DIPOLE ANTENNA At VHF and UHF, most antenna systems are derived from the dipole or its complement, the slot antenna. Many antennas are based on half-wave dipoles fabricated from wire or tubing. The feed point is usually placed at the centre of the dipole, for although this is not absolutely necessary, it can help prevent hdoublebay - wvfisher - Google Sites hdoublebay. H Doublebay Antennas. "The Pileup" Newsletter Feb 03 with AA4S article part 2 Antenna Links Skeleton Slot Antenna ... In September 1995, a 4 element 40 meter KLM log-periodic-yagi was being used by AA4S as a 17 meter antenna for casual DXing with reasonable success. TWIN SLOT ANTENNA STRUCTURES - MED Home TWIN SLOT ANTENNA STRUCTURES For the far infrared spectral region, there is an incentive for using planar antennas rather than bulky, expensive, metallic waveguide structures [1]. One such planar structure is the slot antenna [2], which in its simplest configuration is simply a narrow rectangular slot cut into a sheet of conductor (see Fig. 4.1

diy - Slot antenna for 2 meter mobile - Amateur Radio ... My primary vehicle is a Smart car, with a roof that's a piece of plastic(100% moon roof). Not the most awesome of cars to use for grounds. I'm building a bumper mounted antenna tower, EMT with some square tube. Earlier today I stumbled across an article on 2 meter slot antennas cut in to satellite dishes.
