<DIV><FONT face=Arial> I have a 2.4m offset dish made from fiberglass, GRP,
and I need to calculate the weight ( approx). Its too bulky to use scales
and I need to get some idea of the counterweight needed. I can
calculate/estimate the volume fairly easily but I cant find a figure for
the density. (Actually I can find a lot of figures by Googling but
they are over a 3:1 range!) </FONT></DIV>
<DIV><FONT face=Arial> I assume that there is a fairly standard mix that is
used for parabolic reflectors, there is a fine mesh embedded in the surface
but I dont see that as a big contributor to weight or
strength.</FONT></DIV>
<DIV><FONT face=Arial> Anyone know the answer? </FONT></DIV>
<DIV><FONT face=Arial> Many thanks, 73 Peter G3LTF
