Uh...Not sure where you are or what you are using, but out west here I
see about 10 VHF fiberglass verticals installed on sites for every one
folded dipole. Not that it makes it right, but that's what I see out
there. There are nice products to stabilize the top of the antenna if
you are side mounting, which is probably a good idea if you are
concerned about movement of the antenna. I've had exposed aluminum
collinear antennas create noise on duplex as well, never dealt with
enough exposed aluminum ones to know their failure spots :)
The antenna is certainly not an area to skimp if you want it to survive.
You'll get lots of opinions here, keep in mind that is just what they
are, my opinion is based on what I've used, replaced, repaired,
troubleshot and continue to buy.
Good Luck :)
