Yes, slightly.
The longer antenna will perform a bit better than the shorter one. It's not a huge difference, but if you are on the fringes of coverage, that little bit can make the difference between getting through or not.
I always recommend our users stick with the longer antennas. Most do, but some still prefer the shorter antennas. That's OK with me, as long as they don't start complaining about my system not working right.
