2 meter skeleton slot antenne

Procedure for assembling BAS Skeleton Slot antenna for ApRES

e propose to examine a VHF array that packs a lot of gain into a small volume. It was first called the “skeleton slot”. Later, when described as a vertically polarized antenna for 80 meters, it was named the DMS or “double magnetic sl 2-meter base-station antenna shown in Figure 1 has the onldreotional gain of a J -pole, but it is more effi- cient. No, it is not a halo --Hisa folded skeleton-slot  At VHF and UHF, most antenna systems are derived from the dipole or its feeding two stacked Yagi antennas with a skeleton slot feed, described later in this  Skeleton Slot Yagi Stack: 2m Skeleton Slot yagi Stack145MHz Skeleton Slot yagi Stack 145MHz Slot yagiThe skeleton slot was developed in the UK for TV use  dipole length of 40.6m for 3.52MHz while EZNEC calculates a length of 41.42m for G2BDQ notes [2] that many amateurs use the G5RV antenna with success The main exponent of the HF Skeleton Slot, other than G2HCG, is Bill Capstick &n a 5 band hf antenna just square and great for a small garden build it yourself Skeleton Slot Yagi Stack: 2m Skeleton Slot yagi Stack145MHz Skeleton Slot yagi  

The Slot Cube The diminutive 10 x 10 x 7 inch 2-meter base-station antenna shown in Figure 1 has the omnidirectional gain of a J-pole, but it is more effi- cient. No, it is not a halo - it is a folded skeleton-slot antenna. Halos are normally horizontally polarized.

In some ways the slot provides more flexibility because it enables the length of the loop to be altered to tune the 2 metre quad to exact electrical resonance. Cross members of the 2 metre cubical quad antenna . The next stage is to join and glue two cross members to make the characteristic ‘X’ of the 2 metre cubical quad antenna. Figure 2. S11 as a function of Frequency for the Cavity-backed Slot Antenna. This cavity-backed slot antenna has a first resonance at about 2.45 GHz. At this frequency, the cavity backed slot antenna is roughly 0.474 wavelengths long - which is roughly the length of a resonant dipole antenna. S11 drops to below -20 dB at this frequency

May 28, 2017 I had a skeleton slot antenna made for the FMBC band back in the 60s. I have seen them used for VHF and UHF in a rough industrial service
