Antenna Gain - Cheap

Psst! Wanna double your Wi-Fi range?

Oh, sure, you could spend 60 bucks for a single Linksys TNC Connector Antenna (HGA7T). The Linksys omni-directional screw-on will get you 7dBi for the WRT-54G. The D-Link competition includes a D-Link's 4dBi omni or 6dBi directional screw-on for $30-$40.

But why spend a fortune?

Tritium has a cheaper solution, says The Register.

Their parabolic reflector can be punched out of a cardboard template. The Flatennaor costs less than £10 ($15). The foil-backed cardboard cut-out acts as a parabolic reflector. Tritium claims it can double the range. Add a second reflector and you could "achieve five times the [usual] range under the right conditions", Tritium says.

For Inexpensive Last Mile Alternatives it's hard to top the Deep Dish Cylindrical Parabolic Template -- it's free. That should get you 10db.

Or try Flat Panels, A Hot Spot on a Dongle, Primestar Dish or The Dish. Just for fun.
