requires two sets of parasitic elements instead of one for the true slot; skeleton slot feedpoint is high impedance and requires matching while the true slot feed is low impedance. Both antennas exhibit wide bandwidth and a single feedpoint. The other advantage that the skeleton slot driven element brings to a stacked yagi 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. Vertically polarized and ... 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
WHY WE STACK We stack Yagis in order to increase the gain over that obtainable from one Yagi and/or to decrease the beamwidth.This is a stack of two horizontally polarised Yagis. The dipoles are arranged to have terminal impedances ofSlotted-Cylinder Antennas References. Uploaded by.

Jaybeam D8-@m Skeleton | QRZ Forums The best source of information that I have found on the skeleton-slot yagi antennas is the 1969 edition of the RGSB VHF-UHF Manual by G. R. Jessop, G6JP. Therein are several pages on the theory and construction of the skeleton-slot yagi antennas. Back in the 1970s, I built a homebrew 2-meter skeleton-slot that worked pretty well.
