I'm re-posting this from the first video because it was so relevant for me, Finally I have the answer to my question, I had used a "U" staple gun on my internet coaxial, this staple just barely fits around causing the coax to be slightly squeezed down, Ive been doing this for years working for ADT and never had a problem, I knew I wasn't pinching it so tightly as to short the dielectric, I was dropping internet connections every few minutes at home and the Comcast boy tried for an hour to convince me that my staples where causing all the problems, but he could not explained how, I insisted he replace the modem, he did and ensured me this would not fix my problem, well that was a year ago and it still works great, But I had never heard of the capacitor effect inside of coax effecting the resistance when the dielectric is manipulated, Thanks!
Hi Ron, Thank you for your presentations, they are quite simply excellent and conveyed in lay terms for most to be able to understand. I live in Australia and would appreciate your opinion on the best spectrum meter to buy for free to air and satellite installation priced under $4000. Regards and best wishes to you sir, Paul
Hi Paul I may take you up on the free room my wife and I have always wanted to visit Australia. I don't have a recommendation on the meter and they are expensive as you mention. Sorry I'm not much of a help. Take care Ron.
Thank you Mr. Kipper for all the videos. I live in an older building that is not cable ready. I would like to run the coaxial cables to each room; however, I have to to across a section of the floor that coincidentally will be re-tiled. I would like to cut the cement slab and bury the cable. I know the cable that has the gel protects it from water intrusion, but cement can be very corrosive. A conduit might be a lot more work, is there any material to cover the cable itself and prevent corrosion or protecting it from the exposure to the cement? When going through the walls should I use a conduit to run the cable? If not should I use the cable that has the gel or just the RG6 quad? Any other suggestions to keep in mind? Thank You,
+Javier Collazo Hey nice to hear from you. Since you are remodeling anyway I would cut a 2 inch slot in the drywall about 15 inches off the floor, drill holes in the studs and run the coax to where ever you need it. Then patch the drywall. Stay out of the concrete unless you can put it in PVC pipe. Good luck on your project and stay safe. Ron
Do you happen to have a video on how exactly data is transmitted through the cables? For instance, how does an ISP send data back and forth through the cable, I'm assuming it has something to do with the hertz frequency and converting the data into I guess some sort of signal so it can go through the cable but not sure what that'd be or how it works.
Kate Yes you can using RCA connections and you would need two cables for the speaker. Component and Composite cables are usually mini RG-59 coaxial cable. The speakers would need RCA connections too not the standard binding post used with a lot of standard speaker wire.Thanks for watching
Hi Ron. Great video. Very helpful. A couple questions: I install a lot of video surveillance. What’s the difference between cctv and catv? Where would I or could I measure 50ohms or 75ohms on coax? As a ham operator we are recommended to use 50ohm rg8x or rg58. Is all rg58 50ohm? What are the differences between rg6/58/8x/59-95%copper sheild in terms of ohms and bandwidth? Surprised that analog camera manufacturers require 95%copper sheild but that wire is not good for many other applications
Hey Curious CCTV is closed circuit TV which generally means security systems where CATV or community antenna TV was originally just over the air transmission using an antenna but today about any provider like Cox or Comcast are referred to as CATV providers which is usually using a combination of coax and fiber to provide the service. As for coaxial cable there are 100's of different types RG-58 is a 50 Ohm cable and used for a variety of application but all video cables used in CATV, security, etc use a 75 Ohm cable because all the video equipment like cameras and TVs are designed around a 75 Ohm input on them so they want to match that with the cable. When we say 75 Ohm they are talking about the cables impedance which is a complex calculation partially based on the frequency of the signal and not something you can measure with a simple Ohm meter which actually measures just the DC resistance of a cable. The main differences in the cables are the size of the center conductors and the amount of braiding used. The dielectric or white stuff in the cable keeps the two conductors spaced apart from each other consistently throughout the cable. When you bend or kink the cable that changes the cable impedance at that point. So avoid damaging the cable when installing it. Hope that helps Ron
Great Videos! I was wondering do you have a MOCA video? I am teaching a class about it and would like to have more information. You have gave me some great teaching points. keep up the good work. Thanks
Hi Darrin no I don't have a presentation on MOCA although it has been on my list of videos to do. Just don't have much time to make videos lately. Thanks for watching Ron
Great videos. I've been working with coax for years, but I never felt like I understood the finer points until I watched your videos (parts 1 and 2).
thank you for all the coax tips.

Great video Ron!
Thanks man I need to redo that video.......it is an old one Ron
If you ever make it to Australia, I have a free room waiting for your use.
Paul
You're the best! So much bad info out there, but I know I can take what you say to the bank. Thanks.
Hey Darren appreciate the comment. I learned long ago I do not know it all there is always something new to learn. Take care Ron

Thanks for the video! Do you have a video on showing how to cut and terminate the coax cable?
Hi Wade here is a link to the Playlist I have 28 videos in there about installing the connectors. Have fun and thanks Ron
@@RonKipperDatacomm1 I truly appreciate the link, thank you very much!
Great Videos! I was wondering do you have a MOCA video? I am teaching a class about it and would like to have more information. You have gave me some great teaching points. keep up the good work.

Is a 90° coaxial adapter/connector a good option for making tight bends?
CM yes I think so there is some loss due to any connector and the 90 degree connectors seem to work well. Ron
Thank you
Hi Razer hope it helped Ron
