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 you could reduce the metal around the slot, and have it still radiate. Pictures of 2m version
The skeleton slot provide an ingenious to feed two stack yagi antennas her is my design
Step 1: Skeleton Slot Radiator
Step 2: Skeleton Slot Radiator Loop
Step 3: Tapered Matching Section
This antennas efficiently and achieve a good impedance match.
Step 4: Making the Element Holder EH789
Step 5: Main Mast Bracket MB456
Step 6: Main Boom Spacing MM123
Step 7: Element Length ER-ED4
Step 8: Element Mounting to Boom
Check all dimensions for proper placement on the boom and element
