I'm about to retro fit a residential TV tower antenna into my new SW
antenna. I would also like to use it for my scanner on it as well. Just a
couple of questions:

1. The first I need to get is the actual antenna to mount. Can I use the
same antenna for my SW and scanner or do I need two different
configurations?
2. If I was go to my local Radio Shack and pick out a new SW antenna,
which one would I look for? I know this particular question is quite broad,
but what I'm looking for is a good antenna array that does not require too
much 'fuss' to install.
3. Grounding the tower itself. Would a 4 foot grounding rod be enough,
or should I look for a longer rod?

Any input would be much appreciated. Thanks in advance.
