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. 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.

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
This antenna is by far the best design of the bunch. This configuration results in an SWR of under 2:1 across the entirety of both the 40 and 20 meter bands. Antenna Winders. Since ladder line can be annoying to work with since it doesn’t coil easily, I decided to build some winders from 1/2 inch PVC pipe to keep the finished antennas ...

Skeleton Slot Yagi Stack: 9 Steps The skeleton slot was developed in the UK for TV use soon after WW2. Someone had worked with slot aerials on aircraft, and the use of a half wave vertical slot in a very large piece of sheet metal, results in radiation very much the same as a horizontal dipole. They then set out to find out how much...

(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.
