Radar Basics - Slot Antennas

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... Horizontaly polarized slot antenna for 2 meters and 70… Antennas for 6 meters. 2 meter verticaly polarized omnidirectional slot antenna, radiates at all vertical angles when mounted over a ground plane.I've worked all VK states plus ZL, JA, KH6, HL5, E51 ,3D2, FK8, and A35 on this antenna. Antennas for HF. 2 Metre Cubical Quad Antenna | Two Meter Quad Design |… 2 metre cubical quad construction. A quad for internal use can be made quite simply by constructing a simple wooden frame.At both ends of each piece of wood a small slot is cut to accommodate the wire. This slot can be cut with a saw, or alternatively it is possible to drill a hole of sufficient size to... Build a 2 Meter Vertical Antenna - Mike's Tech Blog

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 ... THE (VHF) DIPOLE ANTENNA - G-Portál 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

the results. The outcome is the skeleton sleeve fed monopole (SSFM) shown in Photo 1. NEC generated plots for the SSFM are shown in Figure 4. Note the antenna’s improved omni-directional performance when compared to the j-pole’s plots on the proceeding page (Fig-ure 2). Construction The antenna assembly informa-tion and material list shown ...

Skeleton Cone - antenna - Red Wave Radio antenna. It has one high feed point, at least 38 feet/11,6 meters up. From that point two plus two sloping elements are forming a kind of double dipole. The two elements are separated 33 degrees. Each sloping element should be 51 feet/15,6 meters. Ladder line should be 450 ohms. With an antenna tuner it works well on 80 - 10 m. What is your ideal PORTABLE QRPp antenna? - eHam.net I do use it with 2 gull wing radials. It works well when the ground conductivity is average to good. When its poor I use a 9 meter fiberglass pole fed with a 4:1 unun as a all band vertical with as many radials as possible. Near saltwater its a killer antenna. The best 14 to 30 mhz dx antenna that I have ever used is the HF Skeleton slot antenna. 2m skeleton siot yagi stack: i1wqrlinkradio.com The skeleton slot provide an ingenious to feed two stack yagi antennas her is my design Folded Skeleton Sleeve Antennas – high on solder
