Use a Wilson Amplifier without an Antenna Port with the Wilson Universal Connector w/ Velcro Patch 301140 The Wilson Electronics Universal connector with 7' RG-174 cable to connects to all cell phones and air cards via a Velcro patch to Wilson direct-connect amplifiers. Specifications 7ft. RG-174 Cable FME female connector Velcro patch connection Installation instructions The universal connector must be placed directly on the cell phone or cellular data card to work properly.  Attach the universal connector to the cell phone or cellular data card with the VELCRO ® included in the package.   To adjust the universal connector for the best signal, go to a weak signal location where your cell phone registers only 1-2 bars without the universal connector connected. (Be sure the amplier is turned off when checking for low signal.) Then, attach the universal connector to the phone, power up the amplier and you should see a signal improvement of 2 or more bars. NOTE: Many phones take up to 20 seconds to reset the bar indicator. To maximize performance, attach the universal connector as close as possible to the original antenna on your cell phone or cellular data card. For cell phones with an internal antenna, place the universal connector on the back, upper left-hand corner of the phone. *Certain phones, such as the Motorola RAZR, have internal antennas at the base, rather than the top, in which case the universal connector should be attached at the bottom rear of the phone.
