I'd been looking into designs for a Yagi antenna with a 17dbi output, in the hopes that I might increase my Wifi's range a bit. However, I came across a problem; my house is surrounded on all sides by what can only be described as a ton of foresty-goodness (trees and whatnot). Not being one to be told that something is impossible, I had another idea. My idea is to put the antenna on the roof and then point it, above the treeline, towards the only tall thing around, the top of a nearby mountain. I'd then take the same type of antenna and attempt, after a brief hike, to access my home Wifi from atop the mountain. My question is, in open air, how much range can I expect to get out of a yagi of this sort? The peak, according to a few online resources is about 1800 ft above sea level, which for simplicities sake is about how far I would estimate that my house is from the base. In addition, we'll also assume that my house is about at sea level (it's definitely not). So, a little bit of elementary school Pythagorean theorem work, and we find that in order to broadcast to the top of the mountain, I'll need to have a signal that can reach approximately 2500 ft (and some change) from it's source, or nearly half of a mile if you prefer. I've toyed with the idea of an amp of some sort, but I'd like to keep this project safe, and not go shooting microwaves at the top of a mountain like some sort of mad scientist or something.
If anyone has a few suggestions for what I can do, on a budget, to get this kind of range/functionality, I'm open to all ideas. I appreciate you taking the time to read this, and to my fellow U.S. Citizens, Happy Independence Day!
As a side note Firefly has been on the Science channel all day. Heck yes.
EDIT: In case anyone is wondering about intentions, I'd just like to do this for a single day, in order to say that I could. A half of a mile is a long distance though.
