I plan to use a 1/4 wave vertical again, but made in the style of the bazooka vertical used on the first flight. The end of the coax will be stripped back 1/4 wavelength, with the outer shield folded back and split into the four radials. To help keep the antenna from flexing as the payload spins, the ends of the radials will be fixed to the payload box and a straw placed over the vertical element. Without any solder joints it should be much more reliable than my previous attempt at this style of antenna. | I plan to use a 1/4 wave vertical again, but made in the style of the bazooka vertical used on the first flight.
