my small systems that we are doing rmd's in have long cascades. i have one that id 12 mini Bridgers deep, and little rmd towns that is 12 actives from the rmd. 1 btd, 4 bridgers and 7 le's. i did my math in my head and respaced the le's so i could have unity gain as it was impossible with the way they were. it was like going back in time to the early 90's when i transferred here to maintain the very old systems that are trunk and feeder. i replaced all the old 550 magnavox trunks, and le with 1gig arris. respaced what i needed for 750 trunk and 550 distribution. dist is actually 750 too but i keep that secret so engineering doesn't use the extra bandwidth, and cause me headaches being the only tech for 5 systems but its 550 all ofdm with a low pilot and ch 70 agc pilot. the old magnavox actives that were damn near 25 years old still worked great but were only 30mhz rtn, and no agc in the le's except for me. i was lucky being an old timer that started in 330 magnavox systems, was a big change going from node 0 and +1 to this, but that's what i get the big bucks for lol. i really like your channel as it reminds me of things i have forgotten, and do out of instinct after many years, and the new changes explained without a lot of engineering techno babble that get me confused sometimes. the longest cascade i had was 20 actives, but the biggest issue was upstream diplex filter roll off. we had voiceports using cornerstone for phones at 38mhz, but the roll off the us as only giving 16-36mhz of usable bandwidth after the 16th active. lots of service, and maint calls
Glad that you like this video and that it is so helpful to you! Happy to hear that you are sharing it. We try to make content that everyone can absorb at their own rate and time too. Don't forget we have these on podcast as well so the techs can listen to the information from their trucks if they want to. itunes.apple.com/us/podcast/get-your-tech-on/id903366948?mt=2 podcasts.google.com/feed/aHR0cHM6Ly92b2xwZWZpcm0uY29tL2ZlZWQvcG9kY2FzdC8 open.spotify.com/show/4XQH9PhWPcV73wLNVhmO1H
Missed not having you join in. Ron is a legend! Don't miss Dec 13th for "Ask Ron Anything" Tips, Tricks and what not to do in your RF network". Would love your input there.
Wow, when I started plant maintenance in 2019 I had a quick 5-second run down of unity gain and it didn't really stick. This made it much clearer. It makes me miss being out in the plant and fixing Rf impairments. I'm not longer in plant maintenance as I went to the construction dept and became a project coordinator. To answer the question on my longest cascade it would have been 12 amps deep but the plant I'm in now I think our deepest is about 7 amps deep and our avg is 4 trunks in cascade and we avg 3 LEs to a trunk amp bridger leg.
Glad the video was insightful and thanks for watching! Please share it with the new guys who need it. Great to hear about the 12 amp cascade and good to hear your back to a more manageable 4 trunk cascade. 👍
Nice job, men. It's always nice to sharpen the sword with your training topics. Being knee-deep in ESD planning with MSO's, I feel there is a need in the industry to discuss unity gain in terms of the new high gain amplifiers out today being able to squeeze 1.8GHz spectrum expansions into existing legacy system designs and all the aspects involved. I know this is right up the alley of your frequent guest speaker, Mr. Lou Ferrigno Downey.

Thanks for the details and history of your upgrades. And thanks for watching.
I dealt with similar. Was it a company from the East in Canada by chance? I retired two years ago.
Thanks guys. I'll be sharing this video with my Maintenance team so they all have a better understanding. Keep up the great informative videos.

Great idea! Thanks for the feedback and thanks for watching Dave.
Ron seems to have a decent mic and a decent room that doesn't echo 😜
Yes, Ron is a pro all the way around.
