    No, what is below the U is not electrically part of the antenna, just for support. Still it's wasted when it can be used to build another antenna, you only need enough to connect to the main support. Here it comes, don't say it, you'll leave it there. Just don't come crying to me when the first strong wind bends it over and you can't make another J-pole with bent tubing.

    There's something spooky about a large Black woman with 7 pin tube sockets stuck to her forehead.

    Lol. It's inside laying across the guest bed right now. I still haven't gotten it on the roof. But I'll cut the extra off before it goes up, and add a few extra coils to the balun.

    Well it's up there. I took the old dish off the mast and stuck the antenna down in it. Only problem is that it's not exactly straight up and down. The mast is quite a hit larger than the wooden pole, so I'm going to have to come up with something else? Any suggestions?

    The coax will be run directly through the existing hole in the wall just below and to the left of the window.

    i also cut off the excess copper pipe from the bottom and added two kre turns to the balun for a total of five.

    Cut three wedge-shaped wooden shims to stick down into the pipe, then adjust them until the wooden pole is vertical. Otherwise, it's fine. It should last for a few years as is unless a hurricane hits Houston.
    All the world’s a stage, but obviously the play is unrehearsed and everybody is ad-libbing his lines. Maybe that’s why it’s hard to tell if we’re living in a tragedy or a farce.

    Well if a hurricane hits Houston, the last thing I'm worried about is that $50 piece of pipe! LOL

    The shims worked. Now I just need a radio to connect it to.

    Looks like you're all set and ready to go! Well, assuming you have something to power it with.
