SWM with existing non approved splitters

[Mertzen]

Just a thread for people with existing splitters, some of them probably inside a wall. Most of them rated 5-1000Mhz from cable operators but some will be with wider ratings.

NOTE: All were tested in actual SWM LNB installs. Ranging from 4 to 6 tuners. All of them were placed after the PI.
Power passing will most likely fail but might be tested in the future on a 4 tuner system.
Images just as representation

As with all non approved equipment YMMV.

were these just tested during the install or have they been tested for a long duration?

Medium duration without any complaints so far. I don't recommend anyone doing installs with these. Just a testbed.

i agree, i wouldnt recommend it either. i just wonder if they would hold up long term.

Splitters are cheap enough I don't see any reason to risk problems with an untested splitter that isn't rated to handle the required frequencies unless it's someplace nearly impossible to replace, eg in the wall someplace.

"Just to add".. With the early SWM8 testing, I used some cable [1GHz] splitters "for grins".
Two of the exact same model didn't work the same. One passed all eight channels on the SWM Meter, and the other only the first Five channels.
These were all after the PI.

I understand to some extent that there are circumstances where existing splitters are hidden in walls or other difficult places to reach and therefore it's good to know what might work or not work. On the other hand it's pretty interesting that many of us spend thousands of dollars on HDTV's, Blu-ray machines, audio amps/receivers, speakers, and so on but we cut corners on a less than $10 item.

Or even $3 [+shipping] for a "good splitter".

Can I use one of these splitters or another not shown to split an outlet in my house to SAT 1 and SAT 2 so I can watch and record on different channels? I only have the capability to get one wire from my 4 x 8 multiswitch to this room but would like to be able to record and watch.

[Simmerman]

The short answer is no, but it might work if the tuners are using the same satellite. Once you need to change the channel and one tuner needs the 101 and the other needs the 119, you will get searching for sat signal. Is it a construction issue on the second line issue or and rental issue?

Since we are on the issue of splitters................

I know alot of you are using power passing splitters to combine two 6x8 multiswitches so they are not cascaded. I have done this with no problems but our office will not let us hook up those switches that way anymore. They said the splitters eventually fail. Whats the longest any of you have had this set up and has anybody had any problems with it? I am talking about 5- mhz range of power passing splitters.

Mertzen....Thanks for the heads up on the splitters. Keep track, I would love to know how long these work. I agree, why use these but you never know what kind of situation you will run into when installing.

[rebvision]

Thanks for the info Simmerman. It is a construction issue. I have two lines running from my multiswitch to behind the TV. There must be a break in the line somewhere in the wall since only one of the lines works. I checked the inputs on the switch and they are fine. I guess I will just have to make do with my current setup.

I have head-ends that have been working for 6+ years with split sat connections.

Sure, everything will *eventually* fail, but this is an industry-standard practice.

They will fail sometime between now and forever. :grin:

Seriously though, our stupidvisors make up all sorts of BS as to why not to do this or that, either out of pure ignorance, lazyness or just stupidity, with zero proof to back up their claim.

One of the latest is that you can't run multiple swm splitters on a single line.

Like this LNB-Splitter-Splitter-IRD. The way some houses are prewired, there is a single drop from the attic to the basement. With splitters in the attic feeding all 2nd floor rooms, splitters in the basement feeding all basement and 1st floor rooms. They "claim" that you have to run a whole crap load of lines from attic to basement, as the attic splitter will fail.

Yeah, right.

Mine has been working for a year now with multiple splitters along the path.

Fools. :sure:

Yet, SWM was developed to allow exactly that, and it's even mentioned in some of the SWM docs.

Some people just need to feel important. :rolleyes:
