A3S with 40 meter add on kit
Does the 40 meter addition change the 20 meter reflector beam to the center beam and the reflector
beam to 15 meters? I am assuming the A3S by itself works as the shortest beam is 10 meters the 15 meter beam is the middle and the 20 meter as the longest? TIA |

The driven element is setup to be used as a rotatable dipole on 40 meters. It works a lot better than it sounds. The spacing of the elements on the boom does not change. |

Between the Rotor and the A3s/ and the Dipole getting it up to 40ft should be a real pain. |

Between the Rotor and the A3s/ and the Dipole getting it up to 40ft should be a real pain. It is about the same size & weight as other multiband beams. The 40 M add on seems pretty expensive but I do use it a lot. Also, Mine is mounteds on a tilt-over, crank up from the late 1970's. Two electric winches, no sweat for an old man. Also, there is a Homebrew tilt mechanism... You can check it out at http://dixienc.us/TiltOverGadget/TiltOverGadget.htm I have also found it useful on WARC bands simply by using a tuner. |
