SatLinkST-7000 HDMI to RF Digital Modulator/Encoder Delivers 1080p HDMI Video to TVs as HD ATSC or QAM (J.83B) Channel via Coax Network

These are incredible! I used them to inject Full High Def Video from my Digital CCTV System & and Satellite feed into my antenna and home TV distribution system. I simply tune them to an un-used channel, balance signal levels with the built in level control, add 3db pads if needed, and inject into my distribution amplifiers. Feeds all the TV's in my home plus my Silicon Dust IP Tuners. I have not had the first problem with them. So awesome to be able to tune to one channel and see all my cameras around the house while I'm in bed, tune to another for a satellite feed, plus all the antenna channels with NO interference anywhere. The RF Satellite remotes are setup for the TV in each room and make it perfect! Pause a movie in the living room, and play it in the bedroom or kitchen.

Picture quality is spectacular over distance in buildings, audio is a jumbled mess making the product worthless.

So far so good, its only been running a few days so we will see as others here have complained that it failed in short order. But others have also said grainy picture, and difficult set up.Yet the setup was so simple! I plugged it into my network went to the IP address and set the configuration. The one guy complaining about grainy picture, did you try a signal amplifier? the first TV had a great picture, the one on the other side of the house was grainy. I put in an amplifier before my distribution switch and whala, beautiful picture everywhere. This is radio frequency running down coax, the further it travels and the more splits the more signal degradation you will observe, therefore the more amplification you will need to provide. Too high of power = problem, too low of power = problem. you have to balance your down stream based on your usage. It does give you the option of changing the output power between 70 and 100 DBuV. you get it too high and your drown out other signals, too low and you'll get a crappy picture. 100 was killing other channels 75 is working great for me.The only negative I can report thus far is that it has no option to handle overscan, and it cuts the very edge of the image off. you don't notice it when movies are playing in full screen but I am pushing a computer over it and it cuts the edges of the start bar and edges off. not a deal breaker but just so others are aware.but it is a beautiful 1080P picture, much better quality than I anticipated.

This thing is great. I have 7 TVs hooked up via coax that need to mirror each other. There is a bit of a delay (remote to action) as I have an Apple TV hooked up to it. I still think this is worth it as the picture is great. I also bought a $50 priced modulator (one with blue fins) and the quality was not good. I wish someone would have told me to just purchase this one instead.

If you are looking for a RF modulator that works the first day but fails to work when you reach your destination then look no further. The setup was easy but the 3rd time we attempted to use it we spend hours power cycling it and could not get it to send a signal. We verified all settings and restored the factory defaults but the unit is dead. We are past the return period so now we have a very expensive paper weight. Do not purchase this product unless you like throwing your money away.

I purchased this modulator so I could add a "channel" for my CCTV cameras to my OTA antenna feed. I'm using a Raspberry Pi to display a web page from the DVR in full-screen kiosk mode. It worked great for a TV connected to the combined feed, but I could not get my HD Homerun to display the channel. It would detect the channel, but would give an error when trying to display it in the app. After reaching out to Silicondust support, I learned that it requires both audio AND video on a channel in order to display a channel. It turns out that I had the audio muted on the Rpi. Once I set the volume to a non-zero value on the source, it worked perfectly. I just wanted anyone else who might have a similar need to be aware of this, and not think that it's a problem with the Satlink. Love this thing!

I use this modulator along with a B0976L5C7B. Both modulators have HDMI inputs along with old style video input and stereo audio. The B0976L5C7B is older style analog while the SatLink ST-7000 is the new style ATSC (havn't done much with QAM (J.83B)).A large new style tv shows a large quality difference. The SatLink ST-7000 display's a picture like a HDMI input from the HDMI generation device (I am using a RPI 3B+ and a RPI Zero (1) to generate the HDMI).I have yet to get the SatLink ST-7000 to pass a 5.1 audio signal. The one attempt to use a WD Live to generate a 5.1 audio signal resulted in no audio at all. The RPI's normally convert 5.1 to stereo so that keeps audio working and it DOES seem to be at least Stereo (it says Dolby on the TV).The SatLink ST-7000 has a network interface for programming remotely but the options for Program Title, Program Details & Rating can't be programmed to the downstream TV's (I wrote the company and was told that couldn't be done). The little Screen shows setup if you want to use it and might be better used if after programming would switch to the running broadcast, it just turns OFF now.I took a chance with the SatLink ST-7000 over the VECOAX MINIMOD-2 and other's that cost 2X over the SatLink ST-7000 and I feel the money saved is GOOD! 5.1 sound seems to be a feature missing from all ATSC modulator's at $500 or less as far as I can tell.I normally mix the SatLink ST-7000 with my TV antenna in the attic and I run its output a 70 dBuV which is 1 up from minimum (100 dBuV is Max)NOTE: The IP interface slow's down considerably from time to time normally after some programming change.

I now have 2 of these hooked up to 2 Raspberry Pi's and made a custom in-house TV stations. Setup was easy for me, but some may have issues with all the possible configs. but so far they have worked perfectly. It takes your Raspberry Pi TV station from using Analog to being Full HD. May end up purchasing a couple more.
