I will give you a couple links to get you started, but if you Google "2m ham antenna" there will be thousands of different sets of plans and variations on them that all the HAM guys use on 2 meters. Only a small adjustment to get up to your frequencies. 2m is technically 150Mhz, but due to FCC band allocation, resides between 144-147.99 Mhz.

Most of the time I end up picking the antenna based on my available construction material.
Just a note, I have a couple 2m copper tubing J-Poles I use at home for shooting the shit on local repeaters, seem to work well for me.
