I have a question for those of you who operate with inverted Ls or any other suspended monopole configuration held over a counterpose by a metal support structure. As you are probably aware, a significant amount of current is induced in the support due to its polarization and close location to the driven wire(s) it is holding up. Do you bond this structure to your counterpoise so this induced current can be included in the return? It seems to me that this would improve efficiency and I'm wondering if anyone has experimented with this, or is bonding your tower or mast holding your inverted L. etc. to your radials standard practice?
Note for obvious reasons i'm not including shunt fed towers and other folded monopoles in this question since in those cases the tower must be both part of the driven element and grounded to the counterpose.



thanks,


rob / k5uj
