splitters with DC pass through, and dbs
 

Do splitters with DC pass-through have the same signal loss as those
without.


I've found vague things on the web and just now I found some RCA brand
splitters that said nothign about decibels anyhow. (A lot of splitters
say nothing, but RCA!?)

I would only be using one, but if necessary, I can plug the
powersupply in in the attic and use no such splitter.

If it is a quality unit, passing DC through should not increase the
losses appreciably.

Insertion loss of a splitter varies somewhat with design factors.
DC pass/block is *not* one of those factors.

Another thing I've noticed is that a lot of splitter in bubble-packs
come with milky-clear plastic caps over the threads. Have you notice
that?

This is totally bogus, right?

I've never seen a splitter with a damaged thread, certainly not one
that hadn't been sold yet.

They are shipped from the factory that way. It doesn't take much to
damage the pot metal most splitters are cast from. Drop one and let it
land on one of the ports. There is a good chance that you will bugger
the threads, or crack the casting. Anything bulk shipped without either
cardboard dividers in the tray and soft layers of single corrugated
cardboard or the plastic caps was automatically rejected by the CATV MSO
I worked for. If you toss them into the bins in a installer's truck
without protection, a lot get damaged.

That makes me feel better. Thanks.

You're welcome. It was part of my job to test samples from multiple
vendors. The lower quality stuff was usually obvious, before it ever
hit the test equipment. :)
