This looks super easy after you do it for a few weeks. Moving from fiber construction to coax construction and this is going to be a big part of the job. Balancing and splicing.
Drill definitely saves time especially in outages
Thank you Sir! You are awesome! Appreciate you for sharing this with us 👍👍👍
Amazing video! Thank you very informative new coax splicer in training!
Very nice demo sir🫡. Question though, what is the input level required for that LE?
I keep Test Point compensation off on my viavi and add the 20db in my head. I was trained the importance of checking the input levels, adding the 20 to get the level, was to calculate how much level to attenuate at the foward pad so to not over or under cook the hybrid chips that amp the rf.
I'm on a high split project in TX atm the LEs need input padded to 14db and Minis to 8db.
Any additional level I need to cut to hit my 41db/34db after adjusting the EQ to get a 7db tilt i pad at the interstage.
Very informative!
Great video. Question; at 24:32, your meter shows a low/high freq range of 261-686 Mhz and you say that the level for the low should be 34 & high at 42 dBmV. My private CATV system has a freq range from 57-567 MHz, what would the proper level be for this range and how do I find that out? Thank you!!
Thank you very much. I am currently working as an assistant and learning how to replace and equalize line and hgd. Could you create a video to teach me how to replace and balance hgd?
Great video! Could you do a video showing how to balance a technetix line extender with a Viavi meter?
Dude!! Carpe, my man!! This video is great and the view count is proof. I checked out your channel sooo stoked for more great videos but 😢 alas, my hopes and dreams were crushed. An unforgivable act of deficient content that will never be forgotten.
😂😂jk kinda. Great video man. Thanks again.
Just wondering why you're doing your setup in thermal and not manual? Also wondering why you're not explaining: the manual backoff (what that's for,) OR the agc padding.
Had the same question
The reason I clicked on this was for the manual back off info. That thing is annoying.
@@zlcoolboy I generally run 3dB down from highest point on my high tilt channel. You should have about 9dB delta between full stop down and full stop up.
Good vídeo!
I from Brazil!
I do construction atm, would make double if i could balance. Thanks for the tips.
Great video and appreciate you covering! Im a new MT and this video will help alot to look back at. I had a question on the S1 switch. After balance in switch one, do you go to switch 2 for manual back off and drop levels by 1.2 db, then go to 3 and raise it up to proper levels from there? We went over this in training but wanted to check on this again. I also gathered from a fellow MT that when your in 2 you turn dism all the way to the left then all the way to right and stop in middle, then adjusted down by 1.2db.
Hi. Thanks for the great video. I have a question regarding the readings on your meter. Using the low channel as an example, I see that the output reading is 34 dB, but the test port is -20 dB. Does that mean that the ACTUAL output is 54dB, or does your meter have a setting to compensate for the 20dB-attenuated test port and reading the correct value?
Acterna meter will let you set the 20dB compensation. Most techs don't, but if your job is to change actives all night then it would be prudent to do so.
@@jimmydean8007 Thank you. My Sadelco doesn't have that to my knowledge, but I rarely work on LEs
Question, I see lots of those metal boxes various sizes on poles .How do you know which is a Node or amplifier, can you tell just by looking at the box which is which. What the different sizes mean ? I enjoyed the video
The nodes are bigger than amplifiers, are sometimes painted white and have big loops of fiber near them. The amplifiers are slightly smaller and have four holes coming out of the main box, there are things called line extenders which are smaller than amplifiers but look similar and only have two main holes coming out of the box.
Is that on a high split?
The company I work at repaired the 1ghz GMLE lol
I got fired for using some tips from your video
What? How?
@@strykerzr350 Because he was pretending to be a cable tech when he was suppose to be watching the french fry machine ;-)
@@jimmydean8007 when you don't remove the in power shunt before plugging the power supply back in, you'll no longer have the power supply. Also, removing the power supply cabling from the chase is just a waste of time.
@@MichaelPugh-zx8koA: He put the shunt in after the power pack was installed B: The power pack at the GS7000 would have been more prone to blowing then the PS, but I think you meant DC Power Pack C: fluke was trolling and you took my response seriously. There are some cuts in the video such as he reads the output levels as 47/45 with the mod -20dB offset at 21:02 and after he shows the AGC (which was already in the 1 position) his levels are 39/34. I'm sure this was for demonstration only.
If you follow these steps word for word, you'll probably get fired.
