Topband: Needed: Rule of Thumb

[Shoppa, Tim]

If it is 5 feet high and 50 feet away... I would consider the fence to be a minor enhancement in ground conductivity 50 feet out :-).

I don't think it's at all obvious that you need to move it.

I have a 5' high chain link fence located  50' from where I would like to put up an 80M vertical.  Obviously, I need to move the fence and have plenty of room to move it. On the other hand, I want to minimize the distance I move the fence due to the expense.

Is there a rule of thumb about how far away objects should be located to prevent interference with the radiation pattern of a vertical?

Thanks for your help.
