[Antennas] Grounding question

[DW Holtman]

Hello,

I'm in the process of putting together an inverted "L" antenna. It will 
be about 30 feet high on the vertical section and about 80 feet long on 
the horizontal section. The far end of the horizontal section will be 
around 50 feet high.

My question is about grounding. I have a small yard and this limits me a 
lot on any type of HF antenna endeavor. I'm putting in ground wires, as 
best as I can as far as the property lines will permit. Most of my yard 
is surrounded by a 4 foot chain link fence. Would grounding the fence 
add to the already dug in grounds or mess up the field?

Thank you in advance for any suggestions/help.
