Coaxial cable extension

[cedric249]

Hi all,

I need to extend my coaxial cabling so I can relocate the internet modem to the other corner of the room.
From the wall, the incoming cable is a male connector.

I recently received a 20 ft male-to-male coaxial cable from my ISP.
I was wondering if I should purchase a coupler or an extension (female to male cable)

Ultimately, I'd like to reduce the DB loss when adding the extending cable. Upon some research, there are different color couplers and I don't know which is best for loss reduction.

Thanks!

Your best bet to prevent DB loss is to buy a longer cable and eliminate the need for the couplers. You can probably find them at stores like Walmart, Best Buy, Radio Shack, Lowe's, or Home Depot, or online at Amazon.

Here's a link to a 50 ft cable for ~$13 on Amazon:

Remember 20 ft as compare to the distance from your entry box to the phone pole is a minuscule addition.

The color of the coupler does not indicate loss or quality, although the blue coax couplers seem popular with better manufacturers. I tend to stay away from gold colored fittings with clear inserts. Department stores will probably not carry good connectors. You'll likely find better ones from an electronics retailer or from a reputable online source.

In any case, the coupler loss will mean little if you have a poor quality cable. Make sure you are using a good quality RG6, preferably with compression fittings (vs crimp fittings).
