Sometimes referred to now as a "cantenna".  How times change.  No mineral oil needed for this one.  Came across the link on the Stormtrack Chaser Forum.

Doubtful & probably "can"-not.At that frequency & with your 'rainy' locale it would be tough, but for low cost of parts it might be worth a try.

When I lived 25mi north of Denver in the mid 70's, I built the "metal washers" style yagi antenna (abt 2' long) & this worked quite well so I could steal the early "cable-TV" off-the-air for free (pix was a lil noisy) that was broadcast to subscribers.

Of course, they ran higher power than the Wi-Fi of today, but this MIGHT work for you.

KL7OF,
Unless you really need broadband immediately, you can wait several months for "WiMax" (think Wi-Fi on steroids) to roll out.It's already started here in the East.We're talkin' really fast speeds (70Mbps+) with a range of 20-30mi both in the unlicensed & licensed spectrum between 2-5 Ghz. Should deploy quickly because unlike cell towers that cost $300-400k to install, these smaller installations are only a couple of thosand (not counting land purchase).Only possible delay will be finalizing of the current protocol standard for 802.16a!
The chips are being made by Intel.

Man charged with stealing Wi-Fi signal
Thursday, July 7, 2005
ST. PETERSBURG, Florida (AP) -- Police have arrested a man for using someone else's wireless Internet network in one of the first criminal cases involving this fairly common practice.

Benjamin Smith III, 41, faces a pretrial hearing this month following his April arrest on charges of unauthorized access to a computer network, a third-degree felony.

Police say Smith admitted using the Wi-Fi signal from the home of Richard Dinon, who had noticed Smith sitting in an SUV outside Dinon's house using a laptop computer.

The practice is so new that the Florida Department of Law Enforcement doesn't even keep statistics, according to the St. Petersburg Times, which reported Smith's arrest this week.

Innocuous use of other people's unsecured Wi-Fi networks is common. But experts say that illegal use often goes undetected, such as people sneaking on others' networks to traffic in child pornography, steal credit card information and send death threats.

Security experts say people can prevent such access by turning on encryption or requiring passwords, but few bother or even know how to do so.

Wi-Fi, short for Wireless Fidelity, has enjoyed prolific growth since 2000. Millions of households have set up wireless home networks that allow people to use the Web from their backyards but also reach the house next door or down the street.

Prosecutors declined to comment, and a working phone number could not be located for Smith.

I saw a guy selling these tomato juice waveguides at Dayton this year. I think he was getting $10-$15.
