Thanks in advance.
Just so you know power isn't all that important. Doubling power does not double the range. Doubling power only gets you +3dB on the receiving end. For example I can talk to Los Angeles from San Diego with 10W on my mobile rig which can do 50W. Why use 50W when 10W will do just fine? For around town I use 5W on all the local repeaters and it works just fine.
Here are some recommendations:
I've heard very good things about the flexi-whip
antenna (150 Watt) from reputable members on EXPO.
I personally like Larsen antennas for their quality. Here is a complete catalog
Not sure which antenna you have for middle of nowhere, but I assume it's one of the longer ones. If so, the difference of course will be the effective radiated pattern. For the long explanation click here
. Here is the short visual version see this diagram:
You talking to helicopters or you in the bottom of a slot canyon? The 1/4 wave is best for that (radiating up). For talking across vast flat distances like the desert, the 5/8 wave will be best.

Don’t think anything out there will do a 100 watts off the shelf most I have seen are more like 70 watts max most are 50 watt. 19 1/2" is a 1/4 wave 2 meter antenna very flexible no spring needed if you add a spring you'll have to cut the antenna shorter makes a big difference at 2 meters.
It really depends on the manufacturer. For example, the NMO Larsen antennas are all rated between 100-200 watts. A vast majority of Comtelco NMO antennas
are good for 200 Watts, The Diamond and Comet line vary widely depending on model.
