It's a good 1/4 wave antenna. Motorola doesn't make them, but it's usually one of the big manufacturers.
It's an NMO base, so it will need an NMO mount. The design of that mount, magnetic, permanent, trunk bracket, etc. is up to you.
As for getting "further range", it really depends what you are comparing it to. If you are using a hand held in a car with the flexible antenna, you will see an improvement by switching to this antenna outside the car, on the UHF bands.
I used these for a number of years on GMRS.
