Richard, Before using PVC pipe, I would suggest testing it to see if it absorbs RF (Some do!). Place a small sample in a microwave oven, along with a mug of water to load the oven. If the PVC sample gets significantly warm after 1 minute try another type. Some PVC pipes have fillers added. Metallic fillings will cause problems.
(A neat trick from the crystal radio builders, who can't tolerate losses in PVC coil forms.)

I think you can find all the fittings necessary to build a simple framework, and then just cover whatever portion of it you want with black plastic builders film, or those inexpensive blue plastic tarps found in many discount stores (you may need to cut out the metal grommets on the tarps and replace them with any of several available plastic types.

It came with lots of metal tubes which had to be put together to form the upper canopy support and the legs. It was about 8' x 8' and 6' tall. However, if one replaced the metal tubes with wooden dowel material, something like this would provide a cheap shelter. The corners usually come with a means to peg into the ground, given the winds at a typical beach. For this you might need to find some plastic or other non-conductive tent pegs. Just a thought.............

Is anyone aware of an off-the-shelf option? Has anyone constructed a simple canopy and would like to share their design and/or experience (good and bad)?
