Long Range WIFI (Antenna) Help

[Zeldoz]

Hi Guys,

Backstory:
2 of my friends live on a Caravan site. One has recently moved plots from the front near a main road, to the rear which has a river plot etc. Now, the downside to the beautiful view is there is NO WIFI.

The second of the two living onsite, still remains at the front of the site connected to a Sky hub through a Netgear WIFI extender i provided/installed as a new access point giving his own SSID etc.

Idea:
I want to use directional antenna's attached to a 1ft pole on each of there roofs to give WIFI out the back in the second caravan...There is a line of sight, and the overall distance is approximately 300m (probably alot less my guesstimates are way bad).

From what i understand, i need to purchase 2x HUBS with Omni antenna's to which i can unscrew one on each and screw in a directional omni antenna attached to the roof. These will point at each other to create the link.

I'm looking at the following antenna's as a first setup to test if this would work, if it does i'll invest in some better antenna's.

The other option is two of these?

and a router.. now can i buy ANY WIFI hub with Omni antenna's? Simply unscrew and screw in my external ones? Or is there more to it?

Other than fitting the antennas and making the router act as a repeater what else would be involved? Anything i should know about?

Below is a map outlining the rough area were spanning..

Any advice appreciated.

I would get a pair of these -- http://www.newegg.com/Product/Product.aspx?Item=N82E16833168114 They will allow you to create a 5Ghz network link. Put the river one in router mode and the road one in access point mode. A single etherent cable for each with data and power.

That would also work! How benificial am i going 5Ghz when there is literally 1 WIFI connection within atleast 1000m squared?

Going on my "cost effective" solution is that likely to work?

I have no idea if your solution will work. I have always used hardware like recommended above. That is what it is designed for.

I too would recommend you go with the outdoor bridge devices.

First you must be very careful of cheap antenna, there is no way for a end consumer to verify the specifications. A good indication of a quality antenna vendor is one that actually shows you the graphs of the antenna output patterns. This means they really did test it.

Now it may not actually be cheaper to buy the parts and put it together yourself. The big thing you have not put in your list is the microwave cable connecting the antenna to the radio device. Cheap cable will lose as much as you gain from the antenna. You want to use what is called LMR600. Once you add all these pieces together many times the outdoor bridge will be cheaper. It also tends to be easier to setup because unlike home routers these devices are designed to talk to each other.
