In the US, copper water pipe comes in three grades, K, L and M, in
increasing order of quality/cost. We also have "DWV" copper pipe for
drains
and vents (non-pressure applications, I guess). Same over there?

Question : Would any of the above grades of copper pipe affect the RF
radiation characteristics of the antenna ?



I don't think so -- just the cost. Aluminum, which is less conductive than
any common copper alloy, makes fine antennas.

By the way, please refer to the copper pipe section at

expressed backwards in my original post.)
