I did initially have a thought of wrapping the dipole legs round some 
pvc piping to physically make the thing small but then you run into all 
kinds of problems electrically so might just use it as supports if I 
build a dipole and as insulators as well. the long wire thing was more a 
way to have it kept out of the elements and would make it easier for me 
to mount against the house and given that plastic is a great insulator, 
it would stop any reaction that might occur as a result of coming into 
contact with any down popes.

to impart this pearl of wisdom:

> If you do use PVC or some equivalent, make sure you drill some drain holes

> if it collects inside a pipe up against a bear wire.
> Plastic, or pvc piping works great for insulators as well for dipole ends.
> You can use T junctions for your end insulators, and a heavy duty joiner
> peace for your center insulator if you are making a regular dipole.
