I have purchased a cover from Rocky Mountain Motorworks through Van-Again,
and have been quite satisfied. It is not waterproof, instead it "breathes"
through tiny holes in the fabric. As far as the antenna, it comes with a
grommet that you install yourself where you need it. The cover also has
grommets on the bottom so you can secure it if it is really windy.

If you order the cover from Ken Wilfy there is a 10% discount for all list
members.
