Well not actually. I know this is an old post, but we are doing some chamber testing now on a new antenna and put some legacy SATCOM antennas in the chamber for reference. Every vehicular antenna had at least 5db of gain, some more. The ground antennas were easily hitting 7db some as high as 14db.
A 2.5 db antenna and 20 watts from a man pack terminal is on the fringes of acceptable link margins.
