yes, you can do that. normally you just strip the shield back and leave 1/4
wave of the center conductor exposed. that makes a reasonable 1/2 wave
dipole as long as the shield is at least 1/4 wave long. you can also add
aluminum foil or fold the shield back for 1/4 wavelength over the insulation
for slightly better results.

yes, can't i use a coax as an antenna by trimming its end at the
calculated length lamda=C/f where for example length of wire = 1/8
