Manny, they have a “Lightweight” ext antennae they can sell you for $25, but I’ve gone with a Wilson YAGI 8009 13 decibel ant, ran about $100.
For my phone, out here, I use a Wilson magnetic mount (vehicle) ant, stuck onto the top of the oil tank.
I rec’d the card for my laptop, then son in law inserted the receiver thingy into the desk model so I can use it in the eMachine I use at home.
I pull it out & take it on the road with me.
As you can see, I’m not really up on technical stuff & terms, but I’ll do my best to answer questions . . .
