Default Questions about a 2m J-pole
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 ?
