[Elecraft] NVIS HF vs VHF line-of-sight & CB in 9.0 quakes

[KG7FYI]

Thanks Joe, I do have two of the ARRL Antenna Books but wasn't familiar 
the other references. I'll be sure to look them up.

I'm currently using a multiband dipole that has really impressed me 
given it's poor location and setup. It's obvious I need an "antenna tool 
kit". That would be very helpful for what I need.
