dB loss by joining 2 8ft RG-6 cables

Know this sounds ridiculous but.....

I have 2 RG-6 coax cables each 8 ft long. I want to join them with this to make a 16 ft cable.

How much dB signal loss would I encounter as opposed to using just 1 16 ft cable?

Thanks!

Insignificant.

Typically under 0.2 dB, although after many years of service and depending on the environment, the connections, esp. inner wire can become corroded, so eventually you may need to clean it with emery paper.
