RG-6 coax - straight run or splice?

Bought a 50' coil of RG-6 coax from Walmart to run to the new dish location, but fell about 20 feet short. It was a pain to get it to where it is now - down inside the wall into basement, along stringers, up the chimney cavity into the attic ... was planning on going out the gable vent to the dish on the peak. It's strung almost to the gable - about halfway across the attic.

So, will I lose any image quality if I buy one of those coax splices and another 30 feet of cable? Or should I get a 75' or 100' coil and re-run it?

If there's not noticeable difference, I'd just as soon splice ....

You can easily add a new piece of RG6.

Use outdoor rated compression connectors, and an F81 Barrel COnnector rated for 3 GHz.

Some of my cable runs are direct without splice. Some have splices with good compression fittings and there is no noticeable degradation.

I have one receiver in an awkward place so I used an existing piece of RG59 already in the wall. There IS some degradation of signal strength but it (usually) works. It's the first one to go out when bad weather rolls in.

See How It Goes With A Splice

It is always better to have a straight run, but reality comes into play. Since it would be difficult (not impossible) to re-wire, I suggest that you see how it goes with a splice. You may re-visit the question if you have signal problems down the road.

If the splice using the correct F81 as pointed out, is indoors, you will be fine.

I've seen all kinds of junk coax, and sometimes I have to make it work, so I change the pre-made ends to compression-type and join it with a blue F81 (a.k.a. barrel, coupler, etc) and it often works in a pinch. But I work with IPTV, not satellite.

There's a Facebook group for cable techs where they often post pics of hacked together ends by customers or electricians. The most common problem we see is the centre conductor sticking out way past the threaded part.
