[TowerTalk] Plastic Cutting Boards for Antenna Stuff ?

[Grant Saviers]

Usually some form of high density polyethylene (HDPE) or a variety 
called UHMW - ultra high molecular weight which is quite slippery and 
used as an inexpensive substitute for TFE in sliding bearings, e.g. 
conveyer strips, low speed sleeve bearings, and part handling machines.  
UHMW is not fun to machine because it is so slippery and gummy.

Both are not UV resistant, although it might take a while for thick 
panels to degrade sufficiently to be a problem.  It's biggest advantage 
is it is cheap.  Polyethylene is also a very good RF insulator if 
protected from exposure, but not very strong.
