The MOST important thing is that all the grounds in your house stay as close to 
the same voltage as possible, including your ham shack. By tying your antenna 
to the electrical panel, you keep the rest of the house closer to the voltage 
in the shack as long as the strike comes from the antenna and the connection to 
the panel is BEEFY and SHORT. 

In other words, the voltage in your house WILL rise during a strike. You want 
the whole house to go up together. You DON'T want part of the house (the shack) 
to be at a higher voltage than the rest of the house -- the voltage between the 
shack and other stuff in the house is what can blow stuff up.
