Try the ARRL Antenna Book. In general, symetrical elevated
radials don't radiate. In general, ground mounted radials
are lossy.

I second this. ARRL Antenna Book:
Check pages 2-16 to 2-18 and "The Effects of Ground' which is Chapter 3.
All the answers you need are there.

Newsgroups can be helpful but sometimes only partly. A good text is
your best friend.

Learning this stuff can be a lot of fun. It can be frustrating, too.

Good Luck,
