[TowerTalk] RG-59

[Grant Saviers]

Yes, assuming you mean using the shield as the conductor.  The larger 
the diameter, the greater the bandwidth, thus RG59 shield helps a bit. 
The formulas for diameter vs bw are in most handbooks.  The RG59 
insulation reduces the velocity factor and thus the antenna will be 
electrically longer by a few percent than the usual dipole formulas 
calculate.  NEC based modeling software can model the effects of thin 
insulation like on RG59.

Otherwise, it is a dipole and a choke is a good idea.
