Mauri,

Thanks for taking to time to run the models. Very interesting data.

In past portable/temporary setups I have had, the political duress (wife, 
neighbors, landlord) caused by dangling wires far outweighed the mechanical 
difficulties caused by a center load inductor. I still maintain that an 
inductive loaded antenna is better than no antenna at all!

This discussion has been very helpful to me at least. In this upcoming 
adventure, I will expend a lot more effort making sure that the temporary 
antenna will have hat wires.
