yeah, my memory had it at 950MHz and from the same resource as you — reading the label on the splitter. I couldn’t find anything to corroborate my oft-faulty memory though, and 50MHz seemed REALLY low.

> Probably has more to do with compression than anything else - thus the irritation with Rogers playing loose with the compression and HD vs SD at various times of the day. Does news or talk shows or soaps REALLY need to be in HD, any time - they're talking heads, I REALLY don't need to see that pimple with any more clarity than I do already, vs, say, National Geographic! <gripe>

Compression really makes a bit error visible, for sure, but again there’s a lot of additional information in the signal to help prevent the error from being visible in the first place.

> Think pipe terminator, looks the same. Really, just connecting internal wire with the braid. If you want to see impact, stick a paper clip in. (But a terminator will do a much better job. Whether it matters in one's environment ... YMMV. But if you terminators, use them.)

Kind of, but it’s not a dead short. It’ll be a 75 ohm resistor between the pin and shield. A short would be just as damaging to the signal as an open (RF is weird that way).

> Cool! Good to know! Never looked at that segment for bends. Connectors are inside the Roger's box outside my exterior wall, and inside the house. Hadn't thought of waterproof connectors. Guess humidity would have some role in the connector in the Rogers box. (But then they would probably throw a hissy fit if I changed connectors at that end!)

What Rogers doesn’t know won’t hurt them. What’s even more interesting is that a standard Bic pen barrel is a pretty damn good fit for what they use to secure those boxes, and Bic pen barrels can be made into quick and dirty mouldable tools with a little heat...
