I would contact Gordon @

He is very helpful. I run a amp and external antenna on my truck then I have a antenna that sits on my desk top. Plugs into the rear antenna port.
A couple of weeks ago I was in Remote Montana and set up the amplifier and mag mount antenna on the camp table and establised a data link for a wifi experience on the laptop. Most things are possible with a amp and good antenna.
