How does one construct a bazooka using 75 ohm coax for the radiating

like to find a good use for. Most of it is RG-6 TV coax variant or
such.

The only thing to be concerned about is the velocity factor to obtain
the correct lengths. The impedance is not factor.

That said, before you spend you time and money I suggest you review
Walt Maxwell's evaluation of that antenna at
