Signal Splitters That Block TV Signals..

When I first started doing TV antennas I didn't realize there was any difference between a signal splitter used for over the air Antenna TV signals, and a diplexer, which is used with satellite signals, and I quickly discovered the DC pass through side of the diplexers used for satellite TV prevented the TV antenna signals from passing through them. In this video I explain in more detail what I learned as a result. If you look at the specifications on the splitters you will often see the frequencies they are designed to pass.
==============================================================================
HERE ARE THE NAMES OF SOME SIGNAL SPLITTERS THAT WORKED WELL FOR TV SIGNALS.
Please take note of the frequencies they are designed to pass, to make sure they are okay for your area. Here in Grants Pass Oregon nothing is broad over 700 MHZ
Amphenol BDS1202H ---This one can only pass 5 to 1218 MHZ.
Antronix CMC2002U -----This one can only pass 5 to 1002 MHZ
Regal S2DGV6 --------------This one can only pass 5 to 600 MHZ
PPC PPC-GHS-2E ----------This one can only pass 5 to 1218 MHZ
Electracord -------------------This one can only pas 5 to 890 MHZ
===============================================================================
HERE ARE SOME SPLITTERS THAT HAVE A DC PASS THROUGH THAT (DOESN'T BLOCK OTA SIGNALS).
MSPLT2R1-02 and the MSPLIT4R1-02 This splitter has 4 outputs, and one of them has a DC pass through from 2 TO 2150 MHZ
================================================================================= HERE ARE THE NAMES DIPLEXER MODEL NUMBERS (((YOU SHOULD AVOID))) FOR OVER THE AIR TV SIGNALS, AS THEY ARE DESIGNED FOR SATELLITE TV SIGNALS ONLY!
Holland HCDA-PI
Holland DP02
Holland STVC
Radio Shack 15-1847
RCA D920
You just fixed an issue in 3 minutes that I've been dealing with for years. Thank you so much.
if you aim the diplexers toward one another they will allow dc pass through and your signal to your second tv but you will need to have another two way splitter not diplexer to catch your third tv..... Or allow dc pass through from tv three to the other diplexer at tv one where they must be aimed toward one another to pass dc and signal simultaneously and then use a two way splitter to reach your second tv!! if you need more info please feel free to reach out i have about 20 plus years in satellite and cable work!!
It's also important to look at what range of frequencies the splitter is designed for. Trying to use a splitter designed for satellite (Dish and DirecTV, etc.) for OTA will not work as they typically only pass frequencies above 900MHz. Most splitters for OTA use are rated for use from 5MHz to 90MHz, and they don't typically do any DC blocking.
from my own experience i have learned that using too many splitters, cause attenuation in every split so the last TV would get an signal of perhaps less of 20% and the tuner error correction getting overloaded
Merry Christmas all :)
I think this is the problem I have. In the lounge I have all the TV channels, in the bedroom I only have about half of them but in the music room I ony have 3 channels, (sometimes 4 but they are very pixelated). As there is nothing worth watching on TV anymore, (and the TV in the music room wont retune anymore, I just use it as a monitor for various computers), I'm not bothered. :)
Glad I found another classically trained tinkerer.
I tend to stay away from splitters altogether. I have 2 tv's and 2 antennas.
A happy Christmas from here in the UK. Thank you for the time and effort you put into your videos, they are always a pleasure to watch.
What purpose does a DC pass-though serve in cabling?
Thanks Dave, I have a small box with about 20-30 multiple "splitters" in it. I use one from time to time and I will have to look more closely now.
Merry Christmas Dave!
Thanks a lot once again for another instructional, easy to follow video. I am always looking forward for all your new videos on OTA TV. ¡Feliz Navidad!
Merry Christmas 🎄💫❤️ and happy new year 🗓🥂
This is good to know! I'm planning on putting up a dual antenna setup , so this will really help, thanks! Also, your video quality is GREAT! Holy cow! What camera are you using for the video?
That was very informative and thanks 👍👍 However, and not knowing where you are located, I am in Central Ontario Canada just west of Toronto and we don't seem to receive OTA signals anymore. I did a google search which didn't seem to help much of potential signals.
Some three-way splitters attenuate 5.5db per output while some are a two-way going into a second two-way and split the signal 4db, 7db, 7db.
Additionally, with DTV, don't you also need to be concerned with frequency range (Mhz) and signal loss over distance? What other concerns do you have?
Hey Dave.
could this coax/dc system with dc pass -thru splitters be used as alternative wiring to operate a home cctv camera?
