Customer Review: Great Product, but not perfect
Summary: 4 Stars
I bought this 5.8 Ghz A/V wireless sender/receiver recently and am quite pleased with it. I used this product to transmit the audio/video signal from my Hughes HBH-SA DirecTV satellite receiver to a Zenith 27" analog TV downstairs. The video and audio quality is quite good, but the picture quality is not quite as good as a wired connection (but I think the quality is very close to what it would be with a wired connection). While I am quite pleased with the audio quality, there is a faint buzz in the background--a faint background noise that is barely noticeable, and therefore not a big deal. Also, I get absolutely no interference of any kind. One concern I have with this product: is that 5.8 Ghz cordless phones (which are far less common than 2.4 Ghz or 900 Mhz cordless phones) can interfere with it (although I have not experienced this since I don't own one of these cordless phones). So even though there are far less wireless products on this frequency, I am slightly concerned that I may get interference in the future if someone too close to me buys a 5.8 Ghz cordless phone.
As many people have said, one of the drawbacks to this product is that you must spend a lot of time fine tuning the connection between the transmitter and receiver until you find that "sweet spot." This can be time consuming, and required me to move both the transmitter and receiver to different locations, and even buy a 12 foot RCA composite A/V cable so I could move the transmitter to a location that is closer to the receiver. So, expect the possibility of needing at least one cable that is longer than the cables provided with the product (which are under 6 feet in length).
My biggest issue with this 5.8 Ghz A/V sender receiver was that it was incompatible with the Zenith 27" TV set it was bought for. This TV set had an available RCA Composite A/V input; hence an RF Modulator should *not* have been necessary. Using the TV's Composite input, the video and audio seemed perfect after finding that "sweet spot", but I experienced the vertical hold problem that a few other reviewers have mentioned. The picture would look fine during the show I was watching, but during certain commericals (especially those with white backgrounds) the TV's vertical hold would fail and the picture would flip vertically, sometimes several times. I initially thought this was a reception issue, and hence I spent too much time adjusting the reception betwen the transmitter and receiver, until I realized it was a compatibility issue. Also, the TV (during a show or commercial) would randomly reset the video input, resulting in the TV intermittedly showing the current channel and time (as if I pressed the ENTER key on the TV's remote). I believe the compatibility issue may be the same issue that many people had with certain Zenith TVs and game consoles--it would seem as though the vertical hold problem is a problem with certain older Zenith TV sets (this set was purchased in 1998). However, I am not sure if this problem can appear on non-Zenith TV sets, so it is clearly something that RF-Link needs to address. Most people who reviewed the product don't seem to have this issue, so I don't think the vertical hold problem affects most TV sets. The solution to this problem was to either plug the A/V receiver into one of the VCR's composite inputs, and then view A/V receiver through the VCR on channel 3 or to use an RF modulator. I bought the RF modulator and am using that, to avoid going through the VCR, since going through the VCR prevents me from watching my satellite TV downstairs while someone is recording something. Both solutions convert the RCA composite signal from the A/V receiver, to VHF on Channel 3 (or 4). This conversion eliminates the vertical hold problem, and the resetting problem I described, however, either solution slightly degrades the picture, and converts the audio to Mono. I have no problem with the *slight* quality loss caused by the RF modulation--it is much better than having to tolerate a flipping picture. This vertical hold problem was driving me crazy, so I would have returned the product had I not found a workaround.
One other issue with this product. The remote extender was totally useless for me. Many people have gotten the remote extender to work, but some have not been successful, like myself. Even if I put the IR mouse right in front of the satellite receiver, it still would not work properly. I think it depends on how the A/V transmitter is aligned with the component you are controlling. Fortunately for me, I happened to already own a Terk LF-UNIV remote extender, so I am using this separate product to extend the range of the remote. It works very well.
The bottom line is that this product works very well with great quality, but your experience may very depending on your setup. For me, the drawbacks were that it seemed to take too much effort to find that sweet spot (in my case buying an extra long 12 foot cable for the transmitter to move it closer to the receiver), the product had a major vertical hold issue with the TV set, and the remote extender functionality was worthless. It is annoying having to use two separate additional products (RF Modulator and Terk remote extender) to make this product work properly (when you consider the high cost of this RF Link product)--this is excluding the 12 foot long cable I had to buy which is not an unreasonable expense. Despite those drawbacks, good clear video and audio with no interference is great, since there is no way that I can use a wired connection to watch satellite TV on a TV set on a different floor from the satellite receiver. I simply cannot get a separate satellite receiver for that TV downstairs. Hence I am very happy with this product.

Description of RF-Link AVS-5811 5.8GHz Audio and Video Transmission System with IR Repeater
The 5.8GHz wireless video/audio sender consists of one transmitter and one receiver. This device transmits wirelessly vivid video and hi-fi stereo sound from a VCR, TV set, LD, DVD, VCD, Satellite Receiver or cable set top box to any TV or monitor. It can also be used in conjunction with a camcorder or CCD camera and turns into a wireless security monitoring system. As to the transmission capability, the signal can go up to 400 feet clear light-of-sight and even penetrate wall. With the built-in IR remote extender, it allows the user to remotely control the audio/video sources in the other rooms.The average home entertainment system once consisted of a TV, stereo, and maybe a cable box. Now a modern system may also include a DVD player, satellite receiver, surround sound amplifier, digital video recorder, and an HD tuner, along with a PC designed to serve as a digital hub for certain audio/video functions. The RF Link AVS-5811 takes A/V technology to the next logical step by wirelessly transmitting audio and video signals from these components to any nearby TV, monitor, or stereo system, letting you enjoy vivid video and hi-fi stereo sound anywhere in the house. The A/V sender effectively lets you send signals to components located upstairs, several rooms away, or elsewhere without running bulky, space-consuming cables in the walls or under the floorboards. With the AVS-5811, viewers can watch simultaneous DVD or satellite programming on upstairs and downstairs TVs, or listen to their favorite tunes on stereos in three different rooms--all without wires. They can also use the sender to watch live video from a camcorder or CCD camera in a remote location, whether for security or entertainment purposes. Users who edit video or capture footage from TV programs on their computers will also find plenty to like about the device, as they can easily send the video from their Macs or PCs directly to a living room TV for viewing.
The AVS-5811 comes with a 5.8 GHz wireless transmitter and a receiver with four selectable channels. Unlike more common 2.4 GHz transmitters, the AVS-5811 doesn't share a band with Bluetooth devices, cordless phones, 801.11b wireless LAN networks, and microwave ovens, ensuring a sharp, interference-free video signal. The four channels are also a bonus, as it lets users set up multiple transmitters and receivers in the same area without cross-channel noisiness. In addition, the sender includes a built-in IR remote extender that controls components from a distance, so a user can mute the bedroom TV while relaxing on the living room sofa, for instance. The sender features an NTSC/PAL video system and transmits to distances as great as 400 feet without obstructions. It's also relatively compact at 6.5 by 4.13 by 10.5 inches (W x H x D).
