    100W-rated autotuners that can mount at the base of the vertical aren't too badly priced, if you're OK with staying at 100W. Get 33' or so up, and as many ground radials as you can fit.

    QRO versions, however, are stratospheric...

    Fact is, put up whatever you can afford in the time you have available. Any antenna is better than no antenna. Although fan dipoles are easy to build, it does take some time to tweak them in. A store bought one should be pruned as well, but it will probably work right out of the box and get you going. What ever you decide to do, good luck, and maybe we can chat some day.

    What the hell is an FMBCB bazooka? Yes, it's for TX but would it have massive gains on the receiving side? This peaked my interest since I'm into FMBCB DX.

    What he said. If you have a tuner just get the wire up. I prefer buying wire at the hardware store in 500' spools and picking up some window line and just making a coax balun.
    Some soldering and a few casts with the big pole and you're in business.

    "What the hell is an FMBCB bazooka?"
    Aw cummon, it's a bazooka cut for the FM broadcast band and not very practical. The vertical is a coaxial dipole so it has unity gain and the horizontal has a weird radiation pattern so you never really know where the lobes are.
    "Yes, it's for TX but would it have massive gains on the receiving side?"
    Gain yes, but that depends on which lobe the transmitter is in if it's in any lobe. Massive? Nowhere close to the typical 8dBd gain of an 8el Yagi.
    "This peaked my interest since I'm into FMBCB DX."
    A Yagi such as the Winegard HD6055P and rotor with RG-6U quad shield coax is pretty much your best bet.

    You can pick one up at Home Despot on Pleasantburg Dr., or Costyouplentyco on Woodruff Rd., Greenville, SC.

    Oh crap, the diagram for the vertical didn't come out right but it's basically a coaxial dipole. The top section is a rod connected to the center conductor of the coax and the bottom section is a sleeve over the coax and connected to the shield. A cheap and dirty portable version is made by stripping the outer jacket away the full length of the dipole and the shield folded back over what remains insulating it from the coax itself, the exposed center conductor forms the top element.

    You are assuming I'm not already using an FMBCB yagi with RG-6QS and variable signal amp.
    No, I did not mention it. I just wanted to talk about an FMBCB buzzooker.
    Thanks for the pictures though. I like pictures since I'm kind of visual and it really gets the old gears to grinding through the rust.
