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 in the *ss 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 ....

Splices are made for stuff like this. It won't hurt a thing. You know where it is so if there is a problem down the road you know where to look.

Insertion loss on a barrel splice is minimal. Don't give it a 2nd thought.

If the splice is inside the house where it'll stay dry, I would think you wouldn't have any problems.

Insertion loss for a barrel is typically <0.2 dB. Quite a bit less than a 2-way splitter that weighs in at 3.5dB (give or take).

I knew it was low but couldn't remember the specs.

This is really no different than attaching a cable to a wall plate, like millions of people do. Basically the same difference but different application.

Great - I was hoping that's what I'd hear from all the experts here! Thanks!

Just make sure your barrel has a blue core. Don't put a cheap one in there. Or it could cause a whole world of issues from frying the lnbf to even frying the rcvr

I use splices inside & outside all the time, but I still like to wrap them with Coaxseal if they are outside to keep moisture out even.Never had a problem. Go forth and splice!

What if the splice is underground? Will this be enough to seal it when it rains? (click here)

No. I wouldn't recommend burying any splice but if you have no other options try this -

We used a heat shrink tubing that was supposedly lined with a "special" adhesive/sealant. Honestly, I don't know if it was any different than the standard, adhesive lined heat shrink. It was supposed to be a temporary fix for drop cables until the cable could be replaced. For hardline repair it was "permanent". I had an underground feed to the far bedroom that was spliced and heat shrunk and held up for years. I finally pulled that cable up and replaced it after a dish was replaced several years ago and I decided to replace all the old, original cable (early 90's). I cut that splice open and it was still clean as a whistle. It had to have been in the ground for at least 5 years at that point. Not saying it's good practice, especially buried. But, it's not necessarily going to be an issue in the short term. These are usually double splices because you don't often have enough cable to do a single splice, depending on how the damage occurs.
