Extending cable

I'm wiring up an addition with RG6, and I have a section that I may not
need - I could wire it now and burn up 160' of cable, or I could run enough
to get me to the attic crawl space (20'), and if I did need to use that
location, could use an F-adapter/coupler and run the cables to the basement.
Do I loose anything by using the connector, or should it be a "solid" run?
Thanks.

I managed to drill right through a previous run when putting in a new line
and had to use a barrel connector to hook it up again. There is no
difference in signal strength between the spliced line and the others.

You are always better off having a solid wire run but if you need to
have a barrel connector especially towards the end of the wire run
then it should not hurt. The more barrel connectors you have the
more likely you will run into problems and have more interference
issues (especially if they are not tightened). For the most part you
should be fine.

If it is a dishpro lnbf with a dishpro receiver setup there are
special barrel connectors to use for those. They have blue coloring
on them. I just ordered some a while back from my distributor as
they were required for me to order if i wanted any and were more
expensive because they were DishPro compatible able to pass the 2.2
GHZ of signal.

I hate it when that happens!

In all but extreme circumstances, the insertion loss through a barrel
splice isn't enough to worry about. Other than a spot for potential
failure, the biggest potential problem with barrel splices is Return
Loss. The return loss of a standard F-81 is 15dB at 1GHz. That's all
they're swept to. Not very good at all. Above 1GHz, it goes in the
toilet. Always best to have a continuous run with no splices.
Sometimes that's not possible, though.

If you do have to splice, use "High Return Loss" F-81s (barrels).
Return loss at 1GHz is 35dB, while at 3GHz it's 26dB. Use compression
fittings as well.
