RFAdapter Coax Cable Caps, F Type 75 Ohm Terminator, 5 Pack, Coax Terminator Caps for Unused Ports on Splitter, AMP, Coaxial Cable, Antenna

Excellent terminations

I recently used these 75 Ohm terminator caps to cover unused coax ports in my home and on my splitters. They worked exactly as expected, fitting securely and providing a clean, finished look. The 10-pack was plenty for my needs, and each cap feels durable and well-made. If you’re looking for an easy solution to cap off unused coax connections, this product does the job perfectly.

Worked as expected.

Quality items. Look great

I purchased these terminators for use with a television over the air antenna combiner. These are mechanical, have no electronics, and no moving parts. The serve one function, which is to terminate cable connections in order to prevent signal loss or interference. They are well made: sturdy metal, properly machined threads, stiff conductor wire, smooth and evenly plated surfaces. I needed them because I swap between one and four indoor antennas on and off the combiner, which leaves up to three ports open at a time. I haven't seen a big difference between using them and not using them, but I can see the difference. Every improvement on a television picture. Using them is easy: Line up the stiff wire conductor inside the terminal with the hole in the center of the insulator in the port. Be sure to line them up straight. Push the terminator toward the port, inserting the wire, until the terminator just touches the port. Then thread on until tight. I'm going to order some push-on type connectors to attach to these terminators so that I can just push on and pull off when changing antennas. That would make these perfect. I didn't rate the "waterproof" because I use these inside only. Also, these are a great bargain at the price. Buy them for a better view (and better stereo, too).

The quality of the builds was great and they all installed without issue. I didn't measure the impedance of these but assuming they are accurately described, it will limit the reflections on my open coax ports. Does it help with signal? Maybe. Can I tell a difference? No. But that's the beauty of a digital signal if you have enough of it, it'll be clear. These might help you if you are on the very edge of having a good signal or not.

If you have a coax cable in a room, you know those typical black unyielding cables providing you with cable TV or Internet, and it is not plugged into anything at that end in the room, then put one of these caps on that end immediately. Cable needs to have an end. These caps inform your signals to not travel down this way. It's a dead end right now. And that improves your signals. LOVE THESE!!

I was having some cable/internet issues, small but annoying. After troubleshooting the cable box and modem, I traced all the cabling and tested every connection. What I found is the at the point of home entry of the cable, it feeds through an amplifier unit. This unit had four connections going to the house but only two are being used. There were two sockets left open. Now having handled network troubleshooting many years ago, which is why I still had the test equipment, I remember a rule about a 75 ohm termination on coax cabling. It was the last point I could try before calling a tech out. Screwed the two terminator caps on, and so far so good. The little quirks I was seeing have disappeared. These came quickly and worked great.
