6 meter collinear antenna. Because of the desire to maintain a low antenna profile—plus my unwillingness to make the investment in a tower, beam and rotator—I decided to investigate other approaches to reasonable antenna performance for 6-meter SSB/CW operation. FYI -- This was (many years ago) for science fair I entered. Feb 18, 2020 · Engineer Roger Cox did a wonderful job designing this antenna, and by the comparisons we have done, it is the highest performing of any manufactured 6-meter vertical antenna. Kind of looks like the modern fiberglass antennas See full list on k5nd. The radome enclosure is about 18 feet long containing the 5 antenna elements. This antenna covers 80 to 6 meters with low feed point impedance and will work with most radios, with or without an antenna tuner. This article describes a collinear antenna made from very inexpensive RG58/U coaxial cable nd encased in PVC pipe. It is a heavy duty fiberglass radome style collinear multiband vertical capable of operating on your choice of 6 meters, 2 meters or the 440 ham band. Didn’t win but had a great ant na when I was finished. What follows is the highlights of what I’ve found. . It is approximately 100 feet long, can handle the legal limit, and is easy and inexpensive to build. CO LINEAR ANTENNA DESIGN antenna for average use. Length of the 50-ohm sections does not matter, so long as they are equal, because the 50-ohm sections are matched, and essentially have a 1:1 VSWR. net My 6-meter Yagi stack uses 50-ohm equal length lines to the Q-sections, which are only λ/4 long. uhpw cfo twxae yywqjh jhchdd xgnd wwz vvciion yosku nsb
