Where do you guys buy tubing to make antennas?

    I built a nice looking Yagi to work sats with a full duplex radio, but the elements are made of copper and so bend easily and the antenna is heavy.

    I would like to rebuild it from something lighter, like aluminum. I bought some called "hobby tubing" but that is also very soft and bends easily. Where do you guys buy more rigid aluminum tubing with a small diameter? Or maybe other metal tubing suitable for satellite antennas.
    I saw some places for larger diameter but haven't had luck with anything around 1/4'.

    I find them after season for a dollar and change a piece don't need the high end ones. On the plus side they are already threaded.

    I don't know if this helps but check any local scrap yard.

    One of the reviews on that link says these arrows are fiberglass. So, no.

    I guess that's something that's not on the website :) I'll have to go to a physical Walmart. It might be a good opportunity to combine it with WMPLOTA.

    Mcmaster seems like they have a great selection although not the cheapest, compared to discounted arrows. The copper I used was less than $10 and replacing it with aluminum from Mcmaster will be more than $50 w/o shipping.

    Btw fiberglass is an option (although not the best) because I have 3M copper tape with conductive adhesive. It's certainly more work to wrap it around each rod but it could work.
