Question : 350ft Coax Cable installation for modem

Hi Experts!

I've been given a task to install a Coax splitter, and run a cable to another building (about 350ft run) in order to set-up a Comcast modem there for Internet access.

I don't have much experience with running Coax cable, and have a few questions:

1. Would such a long run still provide adequate signal for Comcast Internet? I'm hoping to get close to their maximum speeds of 50/10Mbps.

2. What kind of cable do I need to use? About 50ft of that run would be outdoors. A model or a link would be appreciated.

3. What's the best kind of splitters I can get for this job? I've heard that regular "off-shelf" splitters are not good for such jobs. A link or a model would be helpful.

4. Signal strength seems to be very good at the source.  Do I need to install any sort of a "signal repeater" in the middle?

Please advise.

Thanks in advance!

Answer : 350ft Coax Cable installation for modem

That should have been

update tbl
set volume = (select avg(b.volume) from tbl b where b.hr=tbl.hr-1 or b.hr=tbl.hr+1)
where volume = 0

This is too simplistic however, but it may suit your needs. It is simplistic because:

If your first hour has 0, it will copy the value directly from the next hour since there is no data prior.
If you have two or more consecutive zeroes, you will end up with some low valued data.  See this example of before/after.

Hr / Before / after
0 / 10 / 10
1 / 0 / 5
2 / 0 / 0
3 / 0 / 15
4 / 30 / 30
5 / 10 / 10
6 / 0 / 15
7 / 20 / 20
