When I email to that address it says "undeliverable"?

Thanks for responding to my posting. I am new to ham. I have a 2 meter
radio mobile. I have been thinking of getting naother one. Is it better
to use base or mobile? Have also been thinking of getting into HF. Is
this more "fun" than 2 meters.

On another issue I have a little room to make a small base station in
my bonus room upstairs. I have a 20 feet or so tower with my tv antenna
on it. Can I mount a 2 or 10 meter antenna on this tower?
I appreciate your advice!
