The Atlona AT14042 HDMI Female Coupler couples two male HDMI cables together, and is designed to prevent signal loss in the connection.
To make full use of the extra space inside the adapter, 18 gauge wiring is used instead of 26-30 or Atlona's previously used 24. Such thickness allows a transfer signal with no loss.
Additionally, top quality materials are used, such as 99.99% Oxygen Free Copper (OFC) conductors and triple shielding technology. The OFC conductors have a silver plating with ultra high conductivity, very low signal loss and degradation, low electric resistance, and great signal transmission. The triple shielding technology rejects EM and RF interference.
And 24k gold-plated connectors ensure a great connection and a very tight grip.
