Ok, let me explain the exact reason I purchased this, and how it helped me...... First...I was trying for the longest time already to setup a antenna that will pick up the channels I watch mostly, but I just couldn't get it right. No matter what I tried, the one channel I watch most, just kept dropping out every few hours, making it too annoying to rely on. So I kept going back to cable/satellite service. But finally I realized that the one channel I watch mostly that I was having the issues with, is actually a VHF channel,, and all these new active antennas I've been using, as strong as they are, they are mostly just focused on picking up high UHF channels. So kinda leaving the few channels that are still on VHF, with major reception issues. So this gave me a new hope, that maybe if I address this, and boost my VHF reception, maybe I'll have better luck with my channel. So I came across here on Amazon, the Antenna Direct, VHF retro kit. That kinda adds these VHF antenna rods, to any UHF antenna, to boost the VHF reception. So of course I got it, it was only like $20 and it said it came with the signals combiner already built in to this vhf antenna. So I figured this is all I'll need. So.....I got it, climbed up to my antenna mast on the roof, connected the existing uhf antenna into this new ones combiner, and the one combined cable ran in to my unit inside. So first thing I did, of course! Was check my one channel that I've been having the issues with. And low and behold it was now 100 strength, and 100 quality. Prefect!! So I figured wow! Done! Finally I can cancel my Dish network service, I have a usable antenna finally!! BUT...........after the initial excitement seceded, and I was scrolling through my channels, I noticed that all my UHF channels that were always coming in perfectly strong. Were now very weak signals, and some channels were now really not watchable anymore, so I realized that the power amp I've always used, isn't passing the power to the Antenna now, cause as I found out quickly online, this Combiner they included ISN'T power pass on ANY ports, so the power is not going anywhere. When I read that I quickly went to the amp part to unplug it, and it was really really hot (this could be dangerous, cause the power basically has nowhere to go!) So after unplugging and disconnecting the amp, I indeed confirmed that all signals were now still exactly the same, so it had no power basically. So the VHF channels all came in perfectly strong and perfect now, but most UHF were extremely low now. So I realized that I basically need a different combiner that DOES have power pass, but only to the UHF port. So......I FOUND THIS!!!! I saw in the photo here that it has a little switch to turn on/off the power pass, and when it's in the on position it's only passing to UHF port. So I thought, perfect! That's what I need. So I received it today. Climbed up to the Antenna again. Used this combiner instead of the built in one. And Walla!!!! It works perfectly!!!! Now I get all VHF and UHF channels perfectly strong. So I can see that the power is indeed passing now to the UHF antenna. I couldn't be happier with this product so far. It does exactly what I needed it to. But with that said, I did only just get it today. So let's hope I stay this happy with it for a while ... show more

    • Great UHF/VHF Antenna Combiner
Glad I ignored the negative review(s). This does exactly what is supposed to do. I have 1 omnidirectional amplified antenna which worked fine except for a few channels. In doing my research I realized the channels with issues are all VHF and they are transmitted from about the same direction vis-a-vis my location, not too far from here. I purchased an antenna with reportedly good performance in VHF, directional, not amplified. Using this UHF/VHF Antenna Combiner, I combined the VHF stations received by the directional antenna with the UHF signals from the omnidirectional antenna, while using the same main coax cable to power the amplifier thanks to the DC pass on UHF. The device also seems to provide excellent signal filtering and separation. While both antennas are capable of UHF/VHF there is no signal interference to notice. If disconnecting the VHF input there is no VHF signal detected from the other antenna, the same goes for UHF input when removed, there is no UHF signal "leaking" via the other input. Finally, the above configuration allows for better antenna positioning since I could optimize UHF not worrying about making VHF worse, and vice versa. ... show more

    • Combiner performs as expected.

Review Image by RBW
This Stellar Labs combiner appears to work as promised. I have 3 separate outdoor antennas, 2 for UHF and 1 for VHF. I feed both UHF antennas connected through a splitter, into the UHF input on the combiner. The VHF antenna is fed directly to the combiner. The output is then connected to an amplifier, which in turn goes into the house. The combiner properly separates the signals prior to amplification. The unit is larger than I expected, but the cover closes over the combiner to protect it from the outdoor elements. I gave it 4 stars because the VHF connector is situated only a 1/4 inch from the edge of the "box" making it a bit of a challenge to tighten the coax lead! Those with large fingers may find this quite difficult. All things considered, an A-. ---EDIT--- Regarding my comment about the VHF connector being close to the edge.... I realized that the combiner itself appears "hinged" inside the box so the connector edge can be lifted up, allowing for the coax to be tightened without the lip or the edge of the box getting in the way!! :-) ... show more

    • only works if both antennas pointed in same direction...
I live in-between cities and close to none, so I put up 2 roof antennas pointed in different directions. This device doesn't work for this arrangement because its inputs are meant to be 1 for UHF and 1 for VHF. I need both inputs to handle both UHF & VHF. As it is, I lose either the UHF or VHF frequencies in either direction. Other than not serving my needs, the device works fine (thanks to answered question that told me power-amplified signals require the device switch to be in the ON position) without causing a lot of signal loss, surprising for a device without amplification. ... show more

    • A better way to Combine VHF/UHF TV Antennas
A better way to Combine VHF/UHF TV Antennas: UHF/VHF Antenna Combiner with F Connection 40-238 MHZ -1.8dB, 436-460 MHZ -1.8dB, 460-865 MHZ <1dB Port to Port Isolation > -25dB Measured in the shack. Average Signal after installation: 5% or more increase in Quality.😀 Cable entry could have been of tight rubber membrane, but is of felt.

    • Great value
I added this to my homemade antenna setup which had the VHF and UHF antennas wired together. Properly combining them with this box seems to have cleared up some interference issues I was getting. Nice, solidly-made box and well worth the money. The outdoor case was nice although I did not need it. The main part can be removed from the plastic outdoor case. ... show more
