We used this kit for a couple of years to wirelessly send our Sky signal from the Sky box downstairs to our upstairs TV. We could still watch SKY on the downstairs TV - the transmitter unit has HDMI passthrough. We used it because it was physically impossible to run any sort of cable between the two TVs. You can control the Sky box from the far-end TV using the standard Sky remote. Transmits up to 1080p.

It worked/works perfectly but we no longer have use for it. 

As-new condition, complete in original box with all docs.

Asking $100 including shipping within NZ. Current new price in the US is US$195 + shipping. Iogear show the price as US$250. 

Please PM me if interested. I will leave this up for a few days and if no interest it will go to Trademe.

EDIT: Looking at the Iogear webpage, I note that our model does not have the small IR receiver bud shown on their page. This was not part of the kit when we bought it - has been introduced quite recently. IR receiver for Sky remote signal is built into the small remote TX box.
