home -brewed 2 meter skeleton slot antenna. In the next issue we will look at horizontally polarized omnidirectional antennas such as the ha lo or squalo, S dipole, wheel types, and turnstiles. Another type of horizontal omni antenna is the Alford Slot covered in "The Slot Radiator Antenna" also in this issue of the QRN. The skeleton slot was developed in the UK for TV use soon after... Here is a close up of the 2metre driven element, which is the actual skeleton slot. It is (a little less than) 5/8 wavelength in the direction perpendicular to the radiation polarization, and about 0.2 wavelength for the driven element part of each yagi. This sets the spacing between the two yagis at 5/8 wavelength too. Slot antenna for 2 meter mobile - Stack Exchange 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 skeleton slot antenna used to be pretty popular on 2-meters and higher frequencies. J-Beam Ltd. (an antenna company in the U.K.) used to make several different models for 2-meters with different numbers of parasitic elements. Basically, the antennas were yagis except for the feed which was a skeleton slot.

THE HENTENNA RE-VISITED - Hamuniverse I was looking at the design and it is remarkably similar to the skeleton slot which also is a rectangular loop but the skeleton slot is fed in the middle of each of the long sides, while the hentenna is tapped closer to one end. I am looking to put up a hentenna on 6 meters. The D2T AAntenna
