Summary: Imperfect Reception
Comment: Works as advertised for the most part... I have the device where the stereo it controls was, and it will occasionally miss a signal that would have been picked up. Somewhat of a minor annoyance since we use a programmable remote. If you can put up with that, it does transmit as advertised.

Summary: Doesn't work as advertised.
Comment: I purchased the RCA D940 Remote Control Signal Sender to replace the built-in remote extender on my 5GHz TV transmitter/receiver system - which is known to have problems. Because of my wireless DSL router, I cannot use a 2.4GHz system.
Though I knew better, but because of the rave reviews I read on the internet, I bought the D940 with a no return policy. In the reviews most people claim, "The unit works as advertised." I disagree.
The technical specifications state that the `Base Unit' works up to 20 feet from the unit it needs to control. I started with the same setup I had with the 5GHz remote system. With the base 18 feet from my DVR and a clear path to the IR receiver, the D940 worked only intermittently. This problem was resolved by plugging in the `Infrared Extender,' and mounting the diode directly in front of the DVR's IR receiver.
The bigger problem is with the `Extension Unit.' As you probably know, most IR systems have a translucent red(ish) protective covering to filter and keep out stray light that MIGHT erroneously receive/transmit or otherwise affect IR signals. This unit's cover is more opaque than translucent. The technical specifications state this unit "can be placed up to 18 feet from where you will be using the remote control." Again, I must disagree. I use my remote no more than 14 feet from the unit, and it simply did not work. I had to lean forward, extend my arm, and precisely aim the remote, and then got only intermittent results. I decided to take the cover off and make sure all was well within the "Extension Unit." It was, but I also discovered more problems with the IR path. The receiving IR component has a metal plate with holes in it, so only about 75% of the signal reaches it. Since I had the mostly opaque cover off, I decided to try the system without it. Eureka! The system worked as I expected.
So that the components were not exposed, and for aesthetic sake, I modified the `Extension Unit.' RCA and I do not recommend anyone make these modifications, but I include them here for completeness. I cut the metal that covered the receiving diode, and then cut a hole in the mostly opaque cover. I then glued a very translucent red piece of plastic to the inside of the cover and reassembled the unit. I can now use the remote to control the DVR from my bedroom without any trouble, and like any other remote. I only have to aim the remote in the general direction of the entertainment system, and it is as reliable as controlling the DVR while in the living room.

Summary: Only little Pyramid that really works!
Comment: We also used the Remote Extender to control a camera at the back of a church. One we got from a National Retailer at a mall, (R.S.), wouldn't go half the distance we needed. We also tried a unit touted to send video and be a Remote Extender, no luck. This unit goes the distance, even when the receiver is sitting behind a short wall. I'm ordering another for my next project.

Summary: Perfect!
Comment: I bought it to use with my TIVO. It has worked great ever since I set it up. It isn't unsightly, either.

Summary: Awesome!
Comment: Exactly what I needed to avoid paying for an extra satellite receiver. I previously used a splitter to send the signal coming from my basement receiver to an upstairs bedroom, but had to run downstairs to change the channel. Now with the RCA unit, I can change channels from the bedroom. Of course it helps that I have an extra remote from a deactivated receiver to keep in the bedroom. The RCA unit transmits through walls and floors with no problem. I don't notice any time delay at all. The units are actually quite small and unobtrusive (maybe 3 inches tall), so my fears of having big ugly cone things on display were unfounded.
