MINIMOD 2 Vecoax | HDMI to Coax Modulator to distribute Your hdmi Video Sources to All TVs as HD Channels Over existing tv Coax Cables

UPDATE: I encountered some issues balancing the MINIMOD-2 output with the OTA channels to all 5 TVs installed in my RV. The primary issue was because I tried installing the MIDIMOD-2 in the back of the RV near my computer, and the boosted OTA feed is in the front of the RV. The TVs near the front would receive the OTA channels and not the MINIMOD-2 channel. The TVs in the back would receive the MINIMOD-2 channel but not the OTA channels. A TV in the middle of the RV would receive channels from both sources. OBVIOUSLY .. this is no fault of the MINIMOD-2. When I installed the MINIMOD-2 up front at the same coax injection point as the OTA feed, I could get everything to work properly. But one thing I didn't think of is that whenever I move the RV to a different campground, signal strength of the OTA stations will change, necessitating the OTA feed to be rebalanced. Fortunately, my OTA antenna signal booster has adjustable GAIN and SLOPE dials, making it quite easy to balance everything with the MINIMOD-2 which also has an adjustable GAIN feature. I did have to move the NUC computer up front to feed the MINIMOD-2 too, which I wish I didn't have to do, but it's really no big deal. So .. I'm still a happy camper! End of UPDATE ..While this VECOAX MINIMOD-2 just arrived today, and I've only played with it for a few hours now, I can certainly say I really like it.After unboxing it, I left it in its default setup (US cable TV output), coax connected it to a TV in my RV, connected & plugged in the power adapter, and then scanned for new cable channels on the TV. It failed to find the MINIMOD output. I didn't bother to trouble shoot that, since I intend to use it on an OTA channel anyhow (so I can combine it with local TV channels for use in my RV, which is not cable friendly while driving down the road, lol). But I will trouble shoot this later. I'm sure I can get it to work one way or another on cable frequencies if I ever need to. It's probably an attenuation issue anyhow.I then accessed the MINIMOD-2 menu and set it up for ATSC modulation using the default channel and frequency. I then rescanned the TV for OTA channels and this time it detected the MINIMOD-2's channel. It displayed the unit's test video image perfectly.Next I connected the amplified roof antenna coax to the unit's RF input and rescanned for OTA channels on my TV. It found the unit's 14.1 default channel but failed to detect any OTA broadcast channels. I then went into the unit's menu and set attenuation to 20 db. I then rescanned and the TV detected 5 of the 50 or so OTA channels that I can pick up from a city about 50 miles away.Now that I know what that OTA broadcast issue was about, I feel confident I can resolve that later and get most of those channels back. I have a HackRF One SDR which I can connect up later to measure the signal levels of everything to assist in resolving that if necessaryNext I made sure my NUC computer was set to output a fixed video resolution of 1920x1080p, and I switched it from 5.1 to stereo audio output. Then I connected the HDMI output of the NUC computer to the MINIMOD-2. Presto - my computer screen appeared on the TV .. minus about 20 pixels all around the perimeter of the screen. That of course was the TVs fault and was easily corrected with a quick change of the TVs default overscan parameter settings.My NUC computer is networked. I use VLC on it to play videos from my Synology NAS servers that I bring along in my RV. I selected a number of ripped DVD and Blu-ray movies to play. The DVD video appeared almost identical to direct video output. The 35 GB Blu-ray movies I played however exhibited the same compression artifacts that one sees on cable & satellite TV (this is the reason I don't subscribe to cable or satellite, preferring instead to just buy the shows & Blu-ray movies I want to watch). But this artifacting is only an issue when at home and watching movies on a VERY LARGE projection screen. In my RV, I can certainly live with this, as it's no different than what cable or satellite TV does to video. But on a big screen at home, I will not tolerate the artifact video you see on cable and satellite TV quality video. Even OTA digital TV broadcasts are a LOT better than cable. And I can't tolerate the horrible quality of Internet steamed video services. My first choice is to simply buy the movies and shows I want to watch on Blu-ray (and sometimes DVD), then rip them to my NAS servers, making it convenient for instant access & to take them all with me on the road in my RV when vacationing 6-8 months a year.Anyhow, I'm quite pleased with this unit. While I would have liked it too be as good as regular local TV digital broadcast stations, I do realize it's not directly broadcasting the video file, but is resampling the video for a second time from the HDMI output. My tests were also done in low latency mode. For the most part, it looks just fine and I'm quite satisfied with the quality (when viewed on these 5 non-top-of-the-line TVs I have throughout my RV). I bought this so I could continue to watch movies while moving around inside and out on any TV while all the TVs remains in sync with each other (well, as close in sync as digital TV gets). Prior to this purchases, my NUC could only play to the TV it was connected to.BTW, I also have an HDHomerun Extended tuner hooked to my RV Ethernet network. So even if I can't get all of the OTA channels balanced into one coax, it won't matter. I will be using my NUC & VLC to play movies and to watch TV through the HDHomerun tuner, to which I have the antenna directly hooked to, thus eliminating the need to combine any OTA broadcasts with the MINIMOD-2 output. It's also desirable to keep the antenna isolated too because part 2 of this project is to add MoCA networking to my coax, and I don't want any of this transmitting out of my RV.I may add additional details as I proceed with this project I started in my RV. I'm also curious to see if I plug this MINIMOD-2 output into a campgrounds cable TV coax if suddenly everyone in the campgrounds will get to watch my movies too, lol. I'll set my channel name to RVHDTV .. watch for it at campgrounds across America that I might be staying at, lol.

I use this unit to send my satellite signal from HDMI to RF cables for all my TV's and an HDR. It is easy to setup and works great. It is well designed.

I have a master antenna system in my home. I have professional amplifiers to amplify the signals for distribution. The antenna ports are balanced to provide optimum signal to my local TVs. I purchased the Minimod-2 to distribute the HDMI signal from my DirecTV satellite receiver to secondary TVs in the house. The secondary TVs are TVs in places like our study or our exercise room where the TV is smaller and the TV does not get used as often as the TV in our den or our home theater. The Minimum-2 seemed like the perfect answer to this problem especially since I did not want to continue to support AT&T with their ever rising DirecTV costs. Eliminating the numerous DirecTV receivers saved a bit of cash every month. We already have a whole home audio system with IR repeaters in nearly every room and these repeaters allow control of remote devices like a DirecTV receiver.Fundamentally everything worked perfectly. I previously had a low resolution modulator that was retired years ago, but most importantly, I had an injection point in my master antenna system. The disappointment was the picture quality. It is noticeably worse than the direct HDMI input. I thought digital was digital, but I guess something gets turned to analog somewhere. I even see light shadows making it look like out of focus analog TV pictures. I thought that the problem might be the HDMI cable so I purchased the absolute best HDMI cable I could find. The new cable did not change anything. I even tested the output of the modulator directly into the TV and still saw the exact same quality picture. I won't say the quality is poor, but it is not as clear and crisp as HDMI directly from the DirecTV receiver. If I had another option in my already wired house, I'd use HDMI over CAT6 to each of the TVs and I'd forget the modulator. In a new installation, the HDMI over CAT6 would be significantly better, but with 10's to 100's of TVs, HDMI over CAT6 is not practical. In a new home, prewired with CAT6, HDMI over CAT6 might be a better option. Maybe the next generation modulator will have a better picture.

I bought this to use in the RV I bought in 2017. I had a satellite dome installed on the roof when I bought it and I already had an old standard definition (SD) receiver from DirecTV, so the way it was installed was to run the satellite cable from the roof through the combination radio/DVD/TV controller on the wall, then to a cabinet where the DTV receiver was, and then from the DTV receiver, through a splitter to distribute the DTV signal to all 3 TV's. All of the connections were made using coax cable and worked well until I had to upgrade to a Hi Definition (HD) receiver because DTV is stopping their SD broadcasting. The new HD receiver has only HDMI or component video out and my set up is coax cable. Fortunately, I had an old RF modulator that I was able to use; it had component in and coax out, but the picture quality suffered considerably. This Minimod 2 replaced the RF modulator and I am astounded by how good the picture is! I was a bit concerned since I couldn't test the unit by hooking it up to a TV directly, because of the way the TV's were installed, so I called tech support and Keith told me to just skip that part and install it. He also gave me some hints about what to do if the TV's couldn't identify a channel. It took a while, and I had to set up each TV individually, but they all did find the same channel to operate from. And they are not your normal home TV's - they are made primarily for the RV market; Jensens and Furrions. If you're considering this unit, I say go for it. You won't regret it.
