Bill,

One of the issues in talking about your setup is that you are sending square
waves through coax, something that most of us prefer not to do. The reason
was pointed out in another message, that you have to correctly terminate the
odd harmonics. At low levels, this can be done with resistors. At higher
levels, you have to get crafty to keep the efficiency up.

Personally, I'll be quite happy to keep my silicon inside the house. Since
I'll be running a linear amplifier, I think that's best, anyway.
