The signal loss is because the network cable is affected by radio waves. It is recommended to use better shielding network cable like ATEN 2L-2910 and use Electrically Conductive Adhesive Transfer Tape(ECATT) to bind the RJ-45 connector to isolate the interference from other devices like Walkie-talkies.

Please refer below:

- Prepare about 15cm of Electrically Conductive Adhesive Transfer Tape(ECATT).

- Cut about 1cm of the cover of the network cable

- Make sure the inner side of aluminum foil is conducted.

- Make the aluminum foil clad inside out to the appearance of the network cable.

- Use the Electrically Conductive Adhesive Transfer Tape(ECATT) to bind at the connector.

- Finish
