add antenna to PSP-290 ?

is it possible to add optional antenna to psp-290 receiver? you know, as if it was common radio receiver, where you can add some cable and it plays every station without sHHhhHHshSHHsHSHHShsHshh...
maybe i'm wrong, but some cell phones can hold optional outer antenna, so why gps can't?

PS
anyone has tried maplus just to try how fast it connects?

what depends on how fast psp-290 connect?

they are availiable, but the gps has to have the port, the holux glslim236 has the option to add an external antenna.

You can always use a re-radiating antenna.

But not with the PSP-290.
Not without modding it *hehe*

actually i think u can just stick the re-radiating antenna onto the psp-290 and it will work they only cost about 40 bucks i think im going to give it a try bc i lose connection to satellites often.
