    I was thinking the drawing you posted would be more like a feedline except at a couple of 10 and 12m frequencies. Just a guess.
    You may be limited to a windowline J-pole for 10m. You could build one for 17 and another for 20 and string them up in the trees.
    It's hard to really say without being onsite etc etc.

    Lost all your stuff in 2001 because of anal radio sis? WTH did she do? Give it to Goodwill? If you'd rather not say, I understand. I'm just curious about what people do and what goes through their mind when they are so RELIGIOUSLY dead set against something, especially when it's radio.
    When I was growing up, I had to start hiding radios away from my parents because who the hell needs more than one radio? Right?
    Turns out a distant uncle was a Zenith dealer in N. Africa when the Trans Oceanic was big in the 40s and 50s. This uncle ran a shop and charged batteries (for a price) for customers. The claim was that he was taking the good batteries from new radios the first time they came in for a charge and gave the farmers and other people who had to save for a couple of years to buy a radio in the first place, bad batteries that had to be charged much more often while selling off the nearly new batteries that he got for free to the police and military. So as far as my parents were concerned, radio was dirty.

    well I got a whole jumpble of wires up... tried to do the fan, but couldnt keep the shit from tangling up super bad even with spacers.. so fuck I give up.

    edit 19:09 - well it works well on 40 it seems got a 5/9 in WI and PA. 75 loads up above 3930 but no luck even with a tuner below that did get a 5/6 down to TN on 3980

    Why not just built an inverted vee and use balanced feed line instead of coax. (You can even use TV old fashioned twin lead). Cut the vee for the lowest band you intend to use. Get the feed point up as high as you can and run the balanced line into your station. Then use a tuned (pref a link coupled type) between your transmitter (radios) and the antenna. You should be able to tune up on every band. I used this set up for years and it gave me excellent results. Mine was cut for 75 metres and it worked great on 75, 40, 20, 15 and 10. Nice thing is that if you build it right it is almost invisible. Most people would never notice it.

    I tried building a 5 band parallel dipole years ago, fed with coax into a 1-1 balun. Interaction between the wires made it impossible to tune all the bands. However, For many years I have had a two band inverted parallel dipole here cut for 40 and 75 meters. Low SWR on both bands. Don't even need a tuner.

    I had a Fan Dipole with wires cut for 75M, 40M and 20M. I used plastic coat hangers for seperators. It worked like gangbusters for all 3 bands with-out a tuner and everywhere else with the tuner........ I even made a few contacts on 160M and 6M. I could never get it to work on 60M.... I don't know why.

    Another one I built I used PVC Pipe cut to length for my separators....... for some reason, that antenna sucked.....

    yea wierd how these things work... or not work.

    my whole deal got ripped down anyway, so for now im stuck with just a indoor 20m dipole.

    Just be careful though, at higher frequencies the nulls get pretty sharp. My last inverted vee cut for 80m had a deep null towards Europe on 20m. Therefore it was a terrible DX and contest antenna for me.

    My current vee is on the ground, The snow of October took it away.

    Have you thought of an off center fed dipole? It might not be as good as a fan, but it will be easier to get in the air with out becoming a birds nest..

    Must have something to do with how it was oriented. My 134 foot long dipole works fantastic into Europe on 20m. It runs almost dead on N/S. I have a deep null into the West Coast, so I use the 40m loop for that.
