It seems most new GPS devices do not include a antenna connection port (MMCX or MCX).
Why is this? I do not think that GPS internal antenna technology has advanced to the state to make external antennas useless. When I connect a cheap $2 ebay antenna to my AtlasIV unit, my GPS signal increases significantly.
Regardless, is anyone aware of new GPS devices that offer a GPS antenna port? Preferably with SirfPrima chipset.
Clearly an external antenna can still be useful in difficult conditions or with a coated windshield, but less so than with the pre-SiRFstarIII generation and it probably allows manufacturers to save a $1. Anyway I'm not aware of any current branded GPS road systems that offer an external antenna connector.
