QuickerTek today announced a new version of its popular 5.5dBi antenna line — this time for the 15″ MacBook Pro. The company says this antenna more than doubles the wireless signal strength and range over stock for US$100. “Our new 5.5dBi MacBook Pro Antenna is just what Apple’s faster laptops need to stay ahead of lesser Intel hardware. Double signal strength and range means that our customers can sit much further away from the Base Station or other wireless access point hardware, you’re ‘more mobile.’ Both Apple AirPort and AirPort Extreme users will bask in unprecedented wireless performance,” stated Rick Estes of QuickerTek. “If you’re an Apple AirPort Express user and need more range, then this antenna is your grail,” Estes enthused.
