Advance Communicator Desktop HandsFree / Speaker Phone / Cradle
One way to improve your cellular reception is to use a desktop station or vehicle hands free device that has a built in external antenna port. One such device is the AdvanceCommunicator from AdvanceTec.
The AdvanceCommunicator™ from AdvanceTec is designed to convert your cell phone into a convenient stand alone Base Station / Desktop Speakerphone / Hands Free System. The speaker phone and handset work with both cellular and PTT (Push To Talk) modes. The cradle also charges the phone.
The AdvanceCommunicator comes with a high gain antenna but also has an external antenna port built into it making it easy to improve cellular signal strength by adding an antenna such as a Yagi or magnetic mount.
The AdvanceCommunicator also comes with software that enables you to operate your phone from a PC. The software allows you to make calls, copy and save caller ID, store thousands of names and numbers, attach photos, assign distinctive rings, update an activity log, keeps a history of calls and more.
The AdvanceCommunicator is available for many Nextel Motorola iDen phones and some Nokia phones.
