    Some Astroplane materials for those interested.
    It was put through a translator into English, so some of the reading is odd.
    Nevertheless, I found it a very interesting read and it speaks to some of the points of discussion that has plagued the AP to this day.
    I see some of the old points of discussion are entering into the discussion of the Top One and New Top One, too. Enjoy.

    It's been a while. Next AP will be all metal.

    I have the homebrew AP back in the air. The fellow I sold it to for the cost of the materials in it no longer needed it. His son was the recipient of the antenna. The son moved away and was no longer using it. It was given back to me for the price of taking it off the push up pole it was on. It has been in the air through thick and thin for 2-1/2 years now between my place and his, and still registers a very good SWR in spite of being CPVC skinned with aluminum duct tape.

    Not bad for what is essentially plastic and some metal foil tape...

    It more or less provides a bit of confirmation on skin effect.

    Thanks, Crawdad.
    I do, from time to time.
    Things keep me busy, and I rarely have the time to play, but I scratch the itch when I can.
    Take care.

    Couldn’t agree more, Jeff.
    Wasn’t Homer in that movie, The Flight of the Phoenix, with Jimmy Stewart?
    If he wasn’t, he should have been!

    Now, a question about the antenna.
    Has anyone tried one using copper wire inside the tubing in lieu of the aluminum tape?

    I haven't but it's worth a try. Only issue that might arise is how it would influence resonance. I don't know, but I think the dimensions affect proximity of the elements to each other which may be critical.

    HomerBB,

    I have a new Targa Astroplane in the garage ready to go up. I currently run a Sirio Gainmaster with good results but want to see if the Targa will work as good or better. I replaced all the fasteners with stainless. I have 2 questions.
    Will the mast lenght affect the swr/performance. The mast will be about 35-40' long.
    I live on the southern end of Lake Michigan and get sustained high winds. Is there a way to secure the ring from moving under high winds. I would perfer not using string or fishing line.

    Thank you,

    Harry

    Some like to isolate the mast at 9' below the ring, however I never did opting only to choke my feedline at that point.
    As for the securing the ring I usually use zip ties, or cable ties as some call them.

    Like this on the V4k ring:

    Thank you for the information. How will the zip ties hold up long term from the ultraviolet light from the sun?

    Go to the electrical dept of a diy store and look for the black UV resistant ties.
