QuickerTek has upgraded the wireless networking for all MacBooks and
MacBook Pros, including the latest crop of unibody MacBooks and
MacBook Pros.

The US$49.95 antenna upgrade
(http://www.quickertek.com/products/macbook_5dbi_extantenna.php)
attaches to the internal Apple AirPort networking card, moving the
antenna up and out of the MacBook case. It also adds a more powerful
5dBi antenna, which again, boosts the wireless range and speed.

There are no changes or additional software to use, so your Apple
laptop works the same before and after the upgrade is installed. The
removeable antenna clips to the screen of the MacBook. The antenna
cable attaches to the internal Apple AirPort card, passing through
either the security slot or the ExpressCard slot — depending on the
MacBook/MacBook Pro. A detailed installation manual and all the tools
required are included with the product.
