see any problems?


Thanks!
Yes, I would be concerned that the entire assembly (F-connector on the coax, F-connector-to-RCA male adapter, and the keystone insert) will be too long to fit inside of a standard box. Remember that you also have to have a 90-degree bend in that coax which will have to be inside the box!


You might want to consider simply soldering an male RCA plug dirctly onto the coax. It is a bit tricky as you have to be careful not to melt the insulation between the center conductor and the shield allowing the conductor to short-out to the shield.

You can get keystone inserts with a female F conector on the "inside" end, and a female RCA connector on the "outside" end. That way you can terminate the coax with an F connector the same way you would for RF applications, and have fewer connections to fail. Here's one example (No connection to the seller), many places carry them by different mfgrs:

They are available in the usual colors if you want to color-code them by signal. The bend radius issue with this type keystone is the same as for an F-to-F type. If your junction boxes are the (usually orange) open-back type for low voltage applications, you can make very gentle 90 degree bends to the keystone.


You can also get keystones that are female RCA outside, and compression terminate directly to the coax on the inside. One less failure point. They use a different type compression tool, however, so I haven't used them. Here's examples from another vendor (both F and RCA types on this page):

Hope that hepls!
