Discone Mounting Pole - Metal or Plastic?

I purchased a discone antenna off eBay.
Does the mounting pole need to be made of a certain material for best performance, or will anything suffice?

Steel?
Aluminium?
PVC pipe?
Wood?

Does it depend on the specific antenna design, or do all discones require a certain type?

So long as it is strong enough and will survive in the local environment then any support will do.

if you are talking about the type that has a "cone" of long stiff wires underneath, where the pole attaches...yeah any pole will do. There is little radiated field under the antenna at that point, so it does not matter much.

Thanks for the replies.
The antenna is linked to in the first line of my original post, and it's similar to what I would think of as a "normal discone", but with wires elements arranged in a disc/cone array instead of a solid piece of copper forming the disc/cone (it's a UHF/VHF discone).

I wasn't sure if the pole would act as another antenna element, especially since it is electrically connected to the cone half of the antenna, but it sounds as though it is irrelevant, so I'll use the PVC pipe I have lying around the house.
