The transmitters can't send to more than 1 receiver which is why I bought 2 ZENNOX AV VIDEO SENDERS on eBay and they were delivered the day following my purchase. Each transmitter has a SCART which has the ability to have another SCART added, so this is what I did. I initially wanted to be able to view SKY in the kitchen and in the bedroom, so connected the second transmitter to the first via its SCART, put both of their 'mouse' (or IR) next to the remote command light on the SKY box and switched them on. The instructions are very simple to understand (well they must be for me to be able to manage them). Both tv's are working great now, and I'm very happy with my purchases - no cables.
They cost £20 each with £4.95 postage.
Hope this answers your query.
