The 2-Meter Slot-Cube Antenna - W6NBC
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 ... 2m skeleton siot yagi stack: i1wqrlinkradio.com The skeleton slot provide an ingenious to feed two stack yagi antennas her is my design Slot antenna parabolic dish based 2m 440 - YouTube a 40 inch slot cut in a parabolic dish, fed with a so239 jumper about 4.5 inches from the end of a slot, yields a stealthy antenna which can be used for 2m and 70cm.

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 ... 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.

A "Hen-Tenna" for 4m - The Four Metres Website A "Hen-Tenna" for 4m. by David G4UNB. Having read about the "Hen-Tenna", an unusual rectangular antenna design for the high HF and low VHF bands, I wanted to try one of these on four metres. TechTalk#101 - DATV - Looking at a “Slot” Antenna for 1.2 GHz Weather-Proofing Slot Antennas You do not want rain or snow entering the slot of either type of the two slot designs that we have discussed so far. So you typ-ically need some type of plastic container or PVC piping to act as a radome for your antenna. Skeleton-Slot Antenna When I mentioned slot antennas to a friend of mine, he imme-
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. 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.
