Is there a way to directly connect an external antenna to either an LG Optimus S or to an HTC Evo? I'm not findng any kind of port or jack on either phone. I have a signal booster system from Wilson Electronics that has an external antenna that goes on the roof, connected by coax cable to an internal amplifier/antenna that sits on my desk. My phone then needs to be within about 10 feet of the internal antenna, in order to exploit the boosted signal. But the Wilson literature mentions that for many cell phone models, they sell "external adapters" that "connect the cell phone or cellular data card directly to the [external] antenna". Their chart doesn't list either the Optimus or the Evo. I'm wondering if that's simply because neither phone has a port or jack that an antenna can be plugged into.
