Hi - I'm an amateur radio newbie - don't even have a license yet (taking the
Technician exam 1/15). I have a Kenwood TH-F6A and I'm looking for an
antenna for use from home. This looks like a good one - and it's in my price
range ;-) I'm wondering what you experts think of it for a beginner?

Also, I thought this might make a good mobile antenna. But the instructions
say don't use a magnetic mount. I'm really not interested in any kind of
permanent mount. Why do they say not to use a magnetic mount?

Thanks in advance for taking the time to answer.
