Coax cables and splitters

I have a two story home and I'm changing the configuration of my fios service (tv & internet) My cabling now comes in to a 4 way splitter (Internet & 3 TV's). I need to change the configuration to be the main coming in to a two way splitter (1 tv & Rest of system) and then a three way (internet and 2 TV's) I need to know what size splitters I need (?? mhz) and if there will be an issue of a two way going to a three way. Thanks for your help

At a minimum use splitters that can handle up to 1 GHZ. Better to pay a couple bucks more for those that can handle up to 2 GHZ, as the three way will need that kind of support.

Wireless Signal Weak - Tap into Outside Box Coax Cable and Convert to RJ45 Somehow?

Garage PC is too far away from Verizon Wireless Router MI424WR.
The cable from the underground comes in at the garage and is tantalizingly close!
Can a 75 ohm video type splitter be installed at the garage and some sort of converter box be installed at that point to convert the signal and provide a hardwire connection to the network card in the garage PC?
If possible, does Verizon have this converter for a reasonable cost or can you recommend an alternative?
Can an extra STB from Verizon be installed and use the "ETHERNET" RJ45 connector on the rear panel?

The underground cable is fiber. You can't tap into that.

Yes. You can tap into the coax coming out of the ONT and use a MOCA bridge to provide an ethernet connection in the garage.
See the following FAQ:

VZ does not sell MOCA bridges. See the above FAQ for sources of MOCA bridges.

No. The RJ45 connection on the STB is not active.

Representing coax cable in Multisim

I am trying to simulate a 50 ft coax cable connected to a signal generator on the left-hand side and a 50 ohm load on the right-hand side. How would I build this using Multisim?

Hi,
The best option for you is to model the coax line as a 50ohm lossless transmission line and just calculate the delay it will introduce in second. You can use the following formula:
delay time = length of the cable/ TEM velocity (3*10^8m/s)
If you want to include losses you have to calculate the RLCG parameters of the coax cable and include them in the component Lossy Transmission Line.
You can learn more about this here.
I attached a design file that includes these components, always make sure that your load is the same as the transmission line characteristic impedance (matched) to avoid reflection.
Hope this helps,

Can I connect a second router to the coax cable.

In my house Verizon fios goes into a box and a coax cable comes out and splits in one direction towards a set top box and in another direction to an Actiontec M1424WR router. An eithernet cable connects the router to a computer. All is well. This works fine.
Now I want to install another computer next to the TV. It sits a long way from the Actiontec, wireless is flakey and i dread the idea of pulling a long cat5 cable through my attic to connect the computer to the Actiontec?
Will it work if I put a splitter on the end of the coax in the room with the tv, run one wire to the stb, and the other to a new router?
Solved!
Go to Solution.

Not a second router ... you want to go to your favorite online retailer (like Amazon.com) and purchase an ActionTEC ECB2200 (also called an HME2200) MoCA Ethernet Adapter. Plug and play and you're all set -- it will automatically link up over the Coax to your ActionTEC router and provide a LAN connection at the second location for you.
You can search the forums for the ECB2200 / HME2200 and you'll find numerous discussions on this device.
I use this in my home network setup and it works great.

What digital coax cable do I need for my sb 5.1 digital (pic attach

http://www.marctv.de/media/soundblaster5rear.jpg
This is my SB Li've! 5. from the back. The black whole is labeled "or digital" .
I have my Z-680 ( 5. Surround Speakers with DD Decoder) attached with 3 x 3.5 mm to have real 5. Sound in EAX Games.
But I want to connect the soundcard with my decoder via the digital coax cable because I do not play anymore.
So what cable do I need to connect my sb 5. digital to my z-680 via coax?
I need a detailed discription so that I can buy one.
And yes, I know that I only have stereo sound when I am not listinbg to a dvd.
But please give me the answer. I could not find it anywhere on the cl homepage.
Is it a 3.5 mm mono to coax? Or what is it's

Yes it's a mono 3.5mm >> RCA adapter (or a stereo 3.5mm >> 2xRCA cable). You need to use the orange socket labelled 'DIGITAL OUT'.

1310 Bridge RG-59 coax cables.

Hello all, hope everyone is well.
The RG-59 coax cables that come with the 1310 bridge are only 1 foot long. Does anyone know where I could get longer cables as the power injector is quite a distance away because there are no close power sockets. Instead of installing new power sockets near to the bridge, we wanted to simply run longer coax cables.
Hope someone can help!

This cable is standard CATV (cable/dish antenna cable) type RG-6 that is commonly available at any radio or entertainment store - It is exactly the same cable that is used to go from the cable TV receiver to the television - Raw cable and connectors are available from places like Home Depot, Lowes, Walmart etc.

1 coax cable - 2 different routers through splitter - 2 different IP addresses -- Possible?

Hello,
I currently have a verizon fios internet connection shared with my family through phones/laptops/desktops/etc. I am also starting a home business which requires constant internet usage and because of this I want a seperate line.
The wiring in my house is a bit weird so I was recommended by a friend to try an alternative method.
So, I'm wondering if the following is possible:
Currently, there is 1 coax running from the basement verizon box up to the second floor to a router. What I would essentially do is have a coax splitter at the second floor which feeds in to the two routers and each having their own verizon account associated with them. One router would have its own IP address for the family and one would be for my business with its own IP address. Seeing how coax has many frequencies, this should be possible but the billing department told me that I would need a second coax cable for a second router. This kind of ruins things completely.
So, I may have just explained it wrong to the representitive on the phone so I'm wondering if this is possible.
TL;DR Is it possible to have 1 coax cable which has a splitter which then feeds into two routers on two different verizon accounts with two different IP addresses.
Thank You.

Do you only want the separate line so as to not have the other traffic or do you want it so that you have a different ip address?
You can get a business fios account, that will give you 5 ip addresses.
You can run a second router off your first router and give it a different subnet that is unique for your business traffic.

Melted Coax cable, Hot to touch 2 way splitter

I lost all my services (TV and Internet) yesterday. When I checked the splitter in the basement it was too hot to touch and the end of the supply coax cable was melting. The service contact's response was , WOW that's not suposed to happen. Hopefully the tech's can repair today. Any ideas what caused this and can it be prevented?

Make sure the ONT is properly grounded. It sounds like a shorted device or coax somewhere. Something should have taken out a safety before a coax "melted" The tech will need to troubleshoot this issue. Anything less would just be an assumption.
If it were my house I would unplug the ONT power and disconnect the battery. Please consult tech support prior to doing this.

I want to buy a new apple tv but it used hdmi cables and my house is only wired for analog. Is there any way I can use the apple tv on analog cables?

Welcome to the Apple Community.
It's do-able, but I don't think it's a great idea.
DVI
Some users with DVI have managed to get their TV's to work with DVI-HDMI cables. DVI carries no audio, so alternative connections need to be explored to enable audio. DVI doesn't necessarily support HDCP as well as other standards used by HDMI (which may or may not be an issue)
Analogue
There are hardware converters that will convert HDMI to various other types of output, however there are some issues with doing so that you should be aware of.
HDCP
HDCP compliant converters will not allow you to watch HDCP protected content such as that from the iTunes Store. Non compliant converters exist but we cannot discuss them under the Terms of Use for these communities.
Resolution and aspect ratio
I'm not aware of any converters that will scale the output from the Apple TV, any TV or projector which is used will need to be widescreen and support resolutions of 720p (Apple TV 2), 720p/1080p (Apple TV 3)

How to connect a MBP to a BENQ external monitor using a HDMI cable and a HDMI to mini display adapter?

Hi, I have just bought a brand new HDMI cable and HDMI to minidisplay adapter and tried to connect my Macbook Pro up. The external display knows it is there but it is not getting any signal. I have tried on another TV and it also says no signal and I also tried using another Mac but it still didn't work.
Can anyone help?

In some versions of Mac OS X, with the Displays pane open, holding the Option key will show the detect displays button in the lower right.
I am using OS X Mavericks. Where did the Detect Displays button go?
You can find the Detect Displays button in the Displays section of System Preferences. Once there, press and hold the Option key to see the Detect Displays button in the lower-right corner. You can click this button to manually detect another display.
Another technique is to sleep and wake your computer, which will send the detect display sequence as well.

I have a Samsung HD TV and I purchased a Mini Display port to HDMI Adapter today. For some strange reason I get no display on my HD tv. I even tried switching a few HDMI cables and nothing popped up. I made sure my computer was updated. Help pls

I have a Samsung HD TV and I purchased a Mini Display port to HDMI Adapter today. For some strange reason I get no display on my HD tv. I even tried switching a few HDMI cables and nothing popped up. I made sure my computer performed all software updates, and I even tried calling Apple Support. They just told me to keep trying different hdmi cables and see if anything pops up. Does anybody know what the problem is? My HDMI cable is from "rocketfish" also my display port is too.

You may have the screen refresh rate set higher than the TV is generally able to track reliably. It may be able to get there most times, but occasionally loses sync because it is out of its nominal range.
I suggest you sit down with the manual for the TV and find out what resolutions at what refresh rates it intends to support through VGA, and make sure your screen settings are near (or below) those limits.

I am trying to play a DVD on my MacBook Pro and transmit it to my TV (use my TV as the monitor) utilizing a VGA cable and adapter for the Mac but the only image that shows up on the TV is the MacBook wall paper, any ideas on how I can transmit to my TV?

I am trying to hook my MacBook Pro to a Sony Bravia TV via DVI to HDMI cable and the TV will not recognize the signal. I have used the same setup with three other TV's, each a different brand with no problem. Any ideas?

Is the TV set to take input from the HDMI connection?
On your computer, if you open the Displays preferences and do not see an Arrangement tab (or there is an Arrangement tab that shows only a single monitor) then there is something physically wrong with your connection. Try clicking Detect Displays just to see if the computer can now sense the presence of the connection. Check your connections.
If you do have an Arrangement tab, and it shows two screens, then click Gather Windows to bring the TV's Displays preferences on to your main screen if the TV is not yet showing an image. Set the proper resolution (probably 720p, 1080i, or 1080p). Set the refresh rate (probably 60Hz) if that preference is shown. You should see a picture at this point. I recommend turning off mirrored displays if it is enabled.
