Hi Mike:
I used military surplus radar absorbing material to stop reflections on a satellite antenna by applying it to the rain
gutter, see:

A sheet of this stuff about 4 x 6 feet weighed maybe 40 pounds. An easy way to confirm it works is to use it to block a
receiver antenna and see how far the signal goes down.
Have Fun,

Hello, Time-Nutters--
I saw a rather expensive GPS antenna made by one of the
big-name GPS survey equipment mfgrs that was mounted
on top of a 12 or 15 inch diameter disc about 3/4 inch thick.
Turns out that the disc is made of some sort of RF absorbent
foam covered by a weather-proofing coating of some sort.
If one were to try to home-brew something like this, where
would a small piece of the RF absorbent material be obtained
without having to spend too much $$ for this experiment?
Thanks for any feedback on this!!
