    The bazooka might be improved by running the feed coax a good way more horizontal, say 8 feet or so.

    Good point. I wondered about this. I usually hang it horizontally, but do not use it often.

    If you have ones that will actually cut the whip, then by all means use them!

    Horizontally would likely work better.

    Not only is it easier to decouple the transmission line from the antenna (by just letting it drop vertically) but horizontal antennas have ground gain that verticals don't. Of course that gain may only be in two broad directions with nulls off the ends of the horizontal doublet, but it can be substantial.

    When dealing with ionospheric propagation and looking for "DX" reports, it's rare that a vertical antenna will do as well as a horizontal one (elevated high enough above ground to make it work). Vertical antennas are more popular for DX work on the lower bands (80m, 160m) because not many can get horizontal ones high enough above ground; but on 10 meters, that's easy.

    Very interesting. This would make a really good side-by-side experiment. I might make this the first of the "serious" goofy experiments! Probably would do it with 2 identical homebrew 10M dipoles and a horizontal run of coax (on the vertical).

    If you want a cool vertical get a ultimax DX 100 (24ft) run it vertical up a Jackite pole. I have been running one on my roof since 2013. I have one for portable use too.

    The whip can be easily shortened by using a hand file to draw some notches and then snap off with a pair of pliers. No power or special equipment needed.
