There are two ways to accomplish this.

1.) Simply run a length of coax directly up. Strip back the shield
to expose a quarterwave upper element and in the stripping back of the
shield, actually roll it back over the jacket below it to serve as the
lower element.

2.) Use a quarterwave length of tube as the lower half, run the coax
up its interior, connect the shield to it at the top of the tube, and
continue the inner coax up another quarterwave.
