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 ?

Here's another antenna test post I dug out of the archives.

********************************************

I did this test a few years ago (minus the Wilson), at least as best
I could. The problem is that when swapping the magmounts the
position might change a little bit. If the position changes a little
bit then the measured field strength may change a little bit also.
Seeing how all of these antennas are very close to begin with
then you have to wonder if the results may be off just a little bit?

Anyway's, I did run the test and attempted to calibrate the results
in db's . The calibration may be off a little bit, but the order from
the best to the worst as I measured IS accurate.

Radio Shack DLX magmount .................... 0db
K-40 .................................................. ....... .8db
Radio Shack 4.5' center load .................. 1.4db
5' Firestik ................................................ 3db
6.5" Hustler top load ............................... 4db
108' Stainless Steel whip ........................ 4.5db
7' Firestik .................................................. . 5db

Of coarse since the time of this test I have found
and measured even better antennas. Of these the
practical ones all use large diameter masting made of
highly conductive material. A large diameter, air spaced
loading coil. This coil is always upwardly located and the
overall antenna height

Damn Tnom, a 102 on a mag mount? You should be whipped. LOL
