--- Quote from: Freedom Kira on October 02, 2011, 07:38:10 AM ---A mountain range does not mean tons of winds. It means a mountain range. Being on a mountain, the team was able to work with less outside interference, because the stuff the wind can kick up does not contribute as much to interference as stuff on the ground might. There's also less stuff around, in general, that would screw around with the signal.
Winds offer more or less interference depending on the amount and type of debris kicked up by the wind. The wind itself is not the problem.
P.S. Way to turn our OP into a female. I would be more careful with the pronoun "she."
Edit: In any case, suggesting that the OP build a satellite dish communication system that extravagant for the simple purpose of streaming videos is unrealistic. Think about all the problems that simply having one would entail. Aside from the amount of electricity and the cost of materials you'd need to cover, you're streaming pirated content over the air through a conspicuous medium. There are probably also legal issues you'd have to look into, just for having the dish itself, but don't quote me on that one.

Not particularly conspicuous, and not really any legal issues either, provided the total power of the wireless aerial does not exceed regulations (which it won't, because you can't buy those). It would simply be an 802.11b/g wireless network, which are perfectly common, and would just show up as such (same as you occasionally pick up other people's wifi hotspots, this will just appear the same). The only difference is it will be a directional antenna, meaning the total power is all concentrated in one direction (thus leading to much greater range), as opposed to an omnidirectional antenna where the power is spread out equally in all directions.
That said, it probably won't be feasible unless you have line of sight between the two dishes, and can guarantee the midpoint of the link will be a certain distance above the ground (I forget how much, it's called the Freznel zone or something like that). If both of those things are true, then an antenna with 12db gain at each end should be enough to achieve reasonable speeds. It will be either difficult or expensive though, so it might be better to just use the internet instead if you can.

3km straight distance, and he could see the club house from her balcony, meaning nothing in between.
edit: lets say she misjudged the distance and it was 4km or 2.5miles in actual, that distance is very achievable even with a 12inches sat dish =P
some people say a 3feet(36inches) sat dish could reach 8miles or 12.9km.
@OP, i'd like to request a pic from your balcony =P

18" Dish for DirecTv
List Price: $189.99
Price: $27.98
You Save: $162.01 (85%)
+ some mods for the dish $50~ ish
+ WLAN card $60~ ish http://www.newegg.com/Product/Product.aspx?Item=N82E16833281002
= $138 x 2 (total: $276)
note: obviously if you already have a WLan router/card then you can skip the option of buying one.
considering you could also hit the internet through this setup you'd be saving a couple of bucks from getting another line.

Note he said 'almost see the club house from my balcony'. He needs actual line of sight between the two dishes, so it'll only be workable if he can definitely set that up. If he can't quite see, then that might well not be good enough.
And again, it also depends on the distance between the dishes and the ground - if the clubhouse dish is too close to the ground, then you might start getting interference, though I'm not sure of what kind of distances are needed at which parts of the link, so that would be worth researching first too.
kitamesume:
3stories above the ground should be enough, and he pretty much can mount the other dish on the roof of the club.
Edit: ah and i`m requesting a pic from the balcony =P

True, I don't expect there will be any real problems with that, but it's worth checking just to be sure, in case there's a small hill in between or something which would decrease the distance between the link and the ground.
