will it out-perform my current I-MAX 2000
Most anything will out perform an I-MAX 2000. (anyone tired of hearing this yet?)
If you're stuck at vertical then a bit of schooling is in order.
It isn't manufacturer's claims or so called "real world experience"
What it comes down to is any gain you get has to come from somewhere else.
Generally I'm more concerned with where the nulls are. That being my complaint with the I-MAX.
The next issue is location and height and location.
Down in a hole a 1/4 wave up as high as practical.
Up on a hill with clear sight lines a 5/8 or 064.
If you have room look into endless varieties of wire antennas.
MOSLEY is one of the oldest most respected antenna companies in the US.
Unfortunately the price reflects this.
Wire antennas are cheap but the learning curve is steep.
Now a personal opinion: Build it , don't buy it. It's the only way to fit an antenna to your specific needs.
Look I even resisted the inevitable photo !!
