Just this. It's ok like this.

I seem to deal often with wireless video Tx/Rx in 2.4 GHz (and not only). 
For $400 you get a Tx and a Rx good for 1000 ft (300 meters) TRIED. Two of
these will pass ethernet. FYI they use no special antennas and video means
DC to 4.5MHz bandwidth in this case, or in LAN terms, 4.5MBps raw
(actually much more with QAM - up to 128 times more without magic but
let's say only 32 times - more than 128MBps raw). This has been around for
2 years or so, and the price is after import and 2 intermediaries. They
also pass audio on top so you can talk to the other side. Questions ?
