Well, I was saying that.

Yes, but now even that doesn't make sense to me.

When I make an inverted L or vertical with the same size 
wire as a dipole, the Inverted L or vertical always seems to 
have about twice the bandwidth (or more) no matter how good 
the ground system is.

Now that I think about it that doesn't make sense, but that 
always has been how it is when I have done it. I always have 
a big bandwidth problem with a dipole.

Something else I missed has been at work. I'm not sure what 
at the moment, but I'd like to learn what.
