Im thinking of getting a 102" whip, I dont think I need the spring
because of where im mounting it. But is it nessesary? Should I get it
with the whip ?

You don't need the spring... and the 102" is unparalleled in
performance if mounted in the proper location... but there are several
major things to consider. The first is location. To have good omni
performance... the whip must be centered on the mass of metal ground
plane. This means the center of the vehicle... in laymans terms... the
roof. That brings us to the second consideration. Do you want an
antenna that tall on you roof. It will be banging everything from trees
to overhangs at the gas station. It is most inconvienient. My personal
choice is the Wilson 1000 magnet for several reasons. It's well made...
has a good strong magnet... and is much better suited/convienient to
roof mounting. I would estimate that its performance is perhaps 80% of
the 102" whip when mounted on that location. Hope that helps.

What about gain antennas such as the common 1/2 or 5/8 wave?

I would venture to say gain antennas would be much better
performers for the other 99.999% of us.

It depends on what 102" you are talking about. Not all 102"
antennas are created equal. Some 102" antennas can actually
be beat by some shorter antennas.

Let the games begin.

Assuming this is a mobile install.....

A 1/2w antenna is not a "gain" antenna and requires a high-impedance
feed. A 5/8w also requires some impedance matching at the base, but
its benefits in a mobile installation aren't realized because of the
heavy loading required (a 5/8w at 11m is about 22 feet high!).

I wouldn't "venture to say" anything of the sort. I have installed
lots of antennas and tuned them up with a FSM. So far I haven't found
a single antenna that can beat a properly installed (and sometimes
improperly installed) 1/4w (102") whip.

What games? You're right. After the last major discussion on the topic
I did some tests and found out that the 102" stainless whips don't
work as well as the 102" fiberglass whips, the difference apparently
due to the ferrous nature of the conductor. But I have tried both
types on the truck and haven't noticed any -practical- difference.

Frank;
A 1/2 wave doesn't have gain over a 1/4 wave?


Sure, if it's standing a full 18 feet tall.

Mounted properly the 102" is king.
