Ron will tell you why we want to use termination caps on the end of our coaxial cables if they are not being used. Just in the last few years are the CATV companies beginning to suggest we use them in our homes.

Thank you for this explanation that I, as a layman, find to be perfectly understandable and relatable. I hope to find some locations that need terminators and will help out my Internet signal to my router.
Hello yes they are just one other way to isolate your CATV cable system. have fun Ron
Good information. I only recently began seeing these installed and for sale in stores. Up until now, I dismissed them as something that wasn't necessary...but now I know why they're used. Thanks again!
Matt Brown Matt good to hear from you! Yes really in only the last 5-7 years have CATV providers started to use them. They really help in keeping unwanted signals from getting into their system.
This is one of the best, easy-to-understand video explanations I've seen out there. Would you considering doing an updated video for this Ron? (i.e.: something that can apply to TWC's Maxx upgrade stuff that is on-going)
+XSFx5 good to hear from you and yes I will add it to the list to redo. That video was one of the first one I did and the audio and video are pretty bad but hopefully the content is still good. Thanks for watching Ron
I always learn something new and important when I watch your videos, information I can use everyday. Keep up the great work!
I suggested termination caps to the Comcast technician who today came to my house.
He either did not know what I was talking about or did not understand.
The physical cable from outside goes down to the basement.
The first Comcast technician 9 years ago put in an 1 to 5 splitter where each of the 5 from the splitter is connected to a cable that goes to various rooms in the house. This pre-wiring was done by the builder.
I am only using 2 of the 5 cables --- cable modem and DTA.
This second Comcast technician instead puts in a 1 to 2 splitter. LOL.
Sigh.
I am going to buy on eBay and buy some termination caps.
Thank you for this video.
Hello they are just one way to stop noise from entering the cable system use them well! Have fun Ron
They say you learn something new every day even though it’s at the end the day I learned something Thanks
Hey Robert use the info well. Ron
love this video so much. But can you upload a video explaining "Voltage Blocking 75 Ohm Terminator" and "75 Ohm Terminator" differences . and when should we use each of them and where. Thank you,
Nice to hear from you I will add it to my list of videos to do. Just don't seem to have much time lately. Ron
Great videos. Most HD TVs are getting a signal from the provider's box via an HDMI cable. The coax connector on the set is not used. Have you heard of an need to use a termination cap in this location?
Not True... Every installation is different. What you state may be predominant in your area - not so in mine.
I do Home Maintenance for folks that cannot afford to pay the Cable Co. Techs. Mostly disabled veterans on a fixed income.
BTW - I don't ask for any compensation, just material expenses. They deserve all of our respect and assistance whenever possible.
It is my experience that very few of those are HDMI from a provider's "box". Most residences around here don't even have a "provider's box".
The service goes straight to the Modem/Wi-Fi then CATV or LAN to the peripherals. CATV to the home system is split off ahead of the modem etc..
Yes we are very rural.
Aircraft communications frequencies are also in that 5 mhz- 1gig range.
Hi Greg that is good to know! Thanks Ron
Thanks for posting this video, very helpful information.
Hi Rabbit yes they are pretty simple in their design and if you have some interference issues they may help.
Ron
Terminators prevent RF signals from being reflected back from the end of an electronic line that would otherwise cause interference. The terminator is placed at the end of a transmission line and will match impedance and minimize signal reflections.
Hey mark thanks for jumping in on the subject. Take care Ron
Hey Ron, by adding the cap or dummy load, do you lesson the signal strength to any of the other components or lines or should these lines be disconnected and labeled at the source if practical. Great stuff Thank You for the great education on all of this material. Your a natural teacher and instructor.
Hi Scott from hat I know the caps do not decrease the signal strength. I appreciate you being out there. Ron
Great video, thanks for clearing this up. One question I still have: I know there is a difference between a weather cap, that has a seal, and a terminator cap. I have 2 scenarios. One is outside, I’d like to cap off another cable companies line. I assume I use a weather cap??? And then I have a scenario like you demonstrated in the video. An unused coax outlet. I assume I use a terminator cap. Would I be correct? Thanks so much.
Luke yes I think you have it. If the splitter is outside and inside an enclosure you could get away with just the termination cap. Thanks for watching Ron
I'm going to use these to see if they increase the performance of my moCA adapters. I have a little more latency than I was expecting. I hope this helps.
Steven I doubt it will help with the letency but a good way to block any outside interference. Ron
@@RonKipperDatacomm1 Thanks for the reply. I'm wondering if a POE filter could cause latency. I had cable internet before, now I have newly installed fiber. I've read that POE aren't needed since the signal won't leak into neighboring connections through an ONT. I expect moCa adapters to add 2 or 3 ms to my latency. It's about 20 ms higher than straight ethernet.
Excellent video! Thank you. If one Cap better than another, which ones do you recommend?
NBo any 75 Ohm cap will work good luck Ron
Just Great Clear Info. Cheers!
Hello use the info well Ron
Should say about using these on satellite dishes, the recievers are sending a lot more voltage back to the dish and can get very hot.
That is good to know hopefully people will see your comment. Have fun Ron
thanks for clearing this up!
+trilobite1985 Glad to help!Ron
Awesome explanation! Still relevant today. Question: I just have cable internet as I've cut the cord on TV cable. I have several lines from my splitter to various TV's. Would it make sense to put termination caps on all the old TV outputs on the splitter?
If you suspect interference from some source it would not hurt to use them. If everything seems OK I would not worry about it. Hope that helps Ron
what you missed is higher freq also = shorter and shorter antennas. inverse relation between freq and wavelength. a good radiator/antena starts around 1/4 wave length. If the head north again to keep up with fios/fiber to the premisis... 2ghz is 12.5cm wavelength. even on the female end/ prongs inside the jack start to also look like a good antenna because at 1/4th of it we are talking 3mm. I know they keep going larger symbol set/ QAM but id bet they push the freq again in the coming years. other reason it doesnt get hot is the inverse square law, theres almost 0 power/even cat tv and the benfit of wire vs air... its still a hella weak signal in most installs though fttp and the house next to the pedestal might beg to differ. actually even traditional head end style with amp in the pedistal might still encounter this... maybe 1998 and in elementry school a young me once had the idea of rabbit ears into the cable jack. only did that once... i still remember the jolt/why i only did it once as well :D ...pedestal was maybe 100ft from where i did this and i know now the line was split from where it entered the house right under that bedroom lol otherwise good video, the point on reflections is pretty crucial. I wonder how long until they go mumi with cat tv. If i understand it correctly dsl introduced vectoring which seems to be along the same lines but as cable signals are straight rf id think they could eventually go with some form of multiple user mimo and count on coax bents and the like to implement the rf tech in cell and wifi stations. trick would be doing so with out obsoleting all their legacy boxes again.
Wow thanks for the input! Ron
The day the cable company installed a splitter, for tv our household began to hear high frequency noise throughout the house. We canceled tv but still hear high frequency.
In the cable box outside the splitter is still attached and one side is not capped. Also all the ports inside our house are also not capped.
Could this be the cause of high frequency noise and can i remove the splitter and cap the lines that were attached to the splitter to solve this issue?
It could help but I would suspect the signal strength coming into the home may need to be increased to make up for the loss of signal due to the splitter. If you remove the splitter and use just one TV and get a good signal that may be the issue good luck Ron
Master, could you explain what would be a power inserter in an HFC network. If this network is energized at 60 or 90 v, because we are not shocked when touching the TAP.
Hugs from Brazil
Hello that could be caused by several reasons and somehow AC is precent on your cable. So I would be double checking all connections looking for any damage in the cable as well as clearing all over head AC lines are clear of your cable (assume your cable is not buried) and make sure the cable is grounded as it enters the building. Good luck Ron
Hey Ron great video this is what exactly I was looking for, question, is it better to cap at the splitter junction in the basement ( in my case) or at the wall ? Every room has an outlet and I will only be using two?Thanks in advance.
If the wall outlet is not hooked to a splitter then you don't need to cap it. If it is it is recommended you cap it and any unused ports on the splitter should be capped as well. It is just one more way to keep interference out of the system. Have fun Ron
@@RonKipperDatacomm1 Thank you for the reply I will Cap them
How about those 90 degree right angle connectors for coax? The type that would allow the cable to connect to a jack at an angle and lie flat to the wall, instead of coming straight out? I Need to use one behind furniture. Do these cause any issues with the signal strength?
Great video thanks for explaining such an interesting topic. Question: I have a 8 way splitter in the basement and coax cables leading to an outlet in each room. Is there a performance difference in putting terminator caps on all the unused outlets VS disconnecting unused the cables from the 8 way splitter and putting terminator caps directly on the splitter?
Hi Matthew I don't know if I have a good answer for you but I don't think it matters. The cap helps isolate the system from exterior noise so as long as it is capped should be good. Thanks for watching Ron
You're best off terminating at the splitter. If a line gets damaged then that outlet cap is useless.
Thanks for the input. Ron
very good explanation!
Thanks Ron
Thanks Alot!
Hi Rexx appreciate you watching Ron
Thanks so much for the info ~
Tuk glad to help you out have a good week. Ron
Hi Ron, I am wondering - what affect do termination caps have on Cable Internet line stats? For example, what would it change - downstream or upstream, signal strength or signal to noise ratio? I am guessing terminating the caps affects downstream signal strength - for example, properly terminated coaxial ports may result in downstream signal strength of 3.5 dBmV, whereas unterminated coaxial ports may result in downstream signal strength of 2.5 dBmV? Is that correct?
I want to move my wireless router from one room where cable is coming in to another room that has my TV, but I want to have my cable modem share the port. Is a splitter on that outlet where the TV is and a termination cap in the "computer" room my best option or am I better to pay extra for the cable company to route another line to that room? I'm guessing they'll just split it in my box anyway.
+Thomas Bihn Thomas I'm not real clear on your question. However if you split the line with a 2 way splitter to feed the other room it should work. I assuming your cable runs are not long, using a quality splitter and making good connections. It will not hurt to try just run some cable along the floor and see what you get. Ron
outstanding video....
Hi Jim good to hear from you! Hope you can use the info Ron
Hi Ron,
Great video and explanation.
There is a vendor on Ebay selling 75 Ohm termination caps for use on unused coaxial inputs on universal disc players, like the Oppos. Do these keep signals from coming into the unit, out of the unit, or both? I assume there is no harm in using one of these? Thoughts? Thanks!
Probably no harm it should block signals from entering or existing a device. Just one more way to eliminate any electrical noise from entering a system. Not sure if anything nearby is causing you issues though. Hope that helps Ron
@@RonKipperDatacomm1
Thank you Ron. Not experiencing any attributable issues. Just precautionary.
Good stuff!
+Tipp Harris Hi Tipp hope you can use the info. Ron
I have an EXTREME connector from the cable company. There are 5 ports with termination caps on them. I want to add another TV in my basement where this connector is at. My problem is I cannot remove the cap. Must I use a special tool?
Hi Dianne you don't need a special tool other than a basic pair of pliers to loosen the cap to remove it. Good luck Ro
Thanks Ron, I guess it was on too tight. I got it off.
Yea they like to tighten them down pretty good. Glad to help.
Ron
excellent.
Man that is an old video and one I should update but glad you could use the info. Ron
just stick a piece of gum on there its about 75 ohms
envy never heard that one..........I would not doubt it probably helps. Ron
I've got a "Dummy Load" living in my house & she's in my bed!
Hey Rick man I hope she did not hear that.........have fun Ron
