02/18/2022-0720 UTC : This is Bill in Northern Nevada. I moved into this area with few TALL trees. I was spoiled previously with tree heights over 100 Ft. I needed a Wide Band Antenna with a good capture area. With memory & research I dug out an Antenna called a Terminated 3 Wire Folded Dipole ( T3FD ) developed by the USN back in 1948. So I built one using material for an Electric Fence- using a roll of 1″ poly tape { having 7 AL wires 22Ga } I made my lowest Fq. at 2.4 MHz so the total length was 120 Ft. with the Poly Tape spaced 16 inches apart using fibre glass rods also bought a Tractor Supply Store. All hardware is stainless steel. The center piece is made using the same FG Rods which are very strong, holding the Resister in place. RESISTER is ceramic ,non-inductive ,350 W @ 620 Ohms & hollow so the FG rod slides through. The Antenna is fed with 600 Ohm ladder line> to a 600 /50 Ohm balun >coax into the shack. Results : Up 40 feet the Antenna is out standing for receive & Xmtr. Loads nicely 160>6 meters. Very Fq agile & the FT-950 loads it w/o a whimper with SWR 1:1 . DX: ZS2 ; EUR ; PACIFIC ; S. Am & stateside. GREAT ANTENNA & cheap to build.. 73
