Considering that it meets Maxwells requirements and is at least a wavelenght of a radiator my expectations are much higher than yours I suspect that the output will exceed that of a 160 M antenna which has a ground plane. A full length vertical is what you are talking about? I also suspect that if I diddn't concentrated so much on small physical size it could easily be uprated to compete with a yagi! Now here do you mean a directional antenna of your kind, or which? Of course if all is already known about radio this would seem impossible but in a few weeks I myself will have a few QSOs to see how it matches up to my expectations. The archives show all the building instruction but it appears that readers have concentrated on nonsensical retorts without reading the content. Art, throw me a bone here. I've looked in the archives a bit, and you've been a prolific poster! I saw a 160 meter vertical you were posting about, but it had a radial system, and I don't think this one does. -73 de Mike N3LI - |

Set it up vertically and secure so that it doesn't fall over. Get two reels of insulated wire preferbly pre wound paired wire on each reel. Join the paired wires Put the joint at the rear of the former with one reel to the left and one reel to the right. Wnd one wire clockwise and then wind counterclockwise the wire from the other reel. Repeat these two functions making sure the overlapped wires stay parallel with each other. When you have completed the length of the spool then join one wire to another wire from the opposite reel. You now have two wires in your hands one from each of the reels. These two wires are what you connect to the transmission line.. Suggestions for the former. Make two cross arrangements using 1/2 inch plastic piping. At each of the 8 ends place a tee connection. Four pipes around a foot long can the join the two sections, Use tees instead of elbows so the antenna is easier to mount. If you want it to be all frequencie: Cut a 1/2 inch plastic pipe in half,' length wise. Make wire loops and fit them over the cut pipe and solder them tight. Place a quick start threaded rod inside the cut pipe with a motor at one end. Make a electrical wiper to place on the quick start thread to make electrical connection to the loops as the motor turns. Connect a meter to one of the start wires and disconnect it from the joint. Place a sowing needle on the other end of the instrument and pierce the wires in sequence until one gets to the coax connection points marking each wire that is connected to the meter. Connect the marked wires to the loop that were made sp electrical contact can be made to the threaded shaft Connect the shaft to one of the wires that consists of the feed points. Rejoin the wire connections at the start point so that now you have a complete electrical circuit starting at the feed points Place assembly anywhere and apply power and have a qso. Now will somebody that is savvy with computors do that excercise that I suggested with regard to tipped radiators and report on it before you make this antenna or start tilting towers around ten degrees sinc the change is not worth it when calculating total gain?

Can you guys tell us the correct way to spell coil former? It's a bobbin made of insulating material upon which wire is wound. Here's one that got a patent: http://www.patentstorm.us/patents/6262650.html - 73 de Mike N3LI - |

I just figure we should only rib Art on the real typos. 8^) Dave K8MN the product of an inferior American education (at least according to Art Unwin) Me too 8^) - 73 d eMike N3LI - |

I can bear it no longer. We have Art the English educated antenna expert
who cannot write the English language,and now a Scot who doesn't know that a Mandrill is a West African Baboon. If you wind Art's wire on a Baboon it is going to get seriously ****ed off.
