I am new to SWL, ham radio and I have am wondering if I could recreate
some of
the high end antennas that I see in catalogs in copper tubing? I would
imagine that copper can be quite a bit heavier than stainless steel or
aluminum. Are there any differences in reception? Does anyone know a
good
resource to learn more?


Copper is the best except for silver. The problems with either is the cost
and mechanical strength. Wind will usually bend copper tubing and it will
not spring back like the antenna grade aluminum.
There is a very slight (probably not even enough to notice) differance for
the beter with copper over SS or aluminum.
If you can keep the wind dammagd down , then go with the copper tubing.
