Grow up. That is an excessive length drop. A standard drop is under
100 feet. You think you know everything, and that the world has to live
by your rules. You don't, and it doesn't. I'll bet you've never even
seen a CATV franchise, or the dozen of pages of specifications agreed to
by both the CATV company and the local government. The CATV company
isn't a Santa Clause machine, and local governments know why there are
limits to the service provided. If there were't, no one could afford to
build or operate a CATV system. You've never designed a headend, or a
physical plant If they build to supply higher port levels, it has to
start at the headend, and requires closer spaced trunk amplifers. The
system noise goes up from all of the cascaded amplifers, and the
equipment runs hotter, withj a very reduced service life. When you can
design an RF distribution system of more than 500 MHz bandwidth and has
over 10,000 output ports, with the gain stabilized to a couple dBmv 20
miles from the headend and over a range from sub zero F to + 100 F then
you can tell me I'm wrong.

One headend I designed and built was only off by .1 dBmv at the test
port on the first trunk amp which was a half mile from the head end. If
you can do better than that, I'll listen to you and your opinions



Cool! You seem to know what you are up to.

Can you put rough numbers around what you mentioned? Like what are
providers legally required to deliver at the far end of the drop?

Thanks.
