Why Use CATV Termination Caps 

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.

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!

They say you learn something new every day even though it’s at the end the day I learned something Thanks

I always learn something new and important when I watch your videos, information I can use everyday. Keep up the great work!

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)

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,

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.

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?

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.

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.

Thanks for posting this video, very helpful information.

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.

Excellent video! Thank you. If one Cap better than another, which ones do you recommend?

Aircraft communications frequencies are also in that 5 mhz- 1gig range.

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?

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.

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

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.

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.

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?

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?

Just Great Clear Info. Cheers!

thanks for clearing this up!

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.

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?

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.

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 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!

very good explanation!

outstanding video....

Thanks so much for the info ~

Thanks Alot!

Good stuff!

excellent.

just stick a piece of gum on there its about 75 ohms

I've got a "Dummy Load" living in my house & she's in my bed!
