Cable Assemblies Now offers the best RF solutions and highest quality products that will exceed expectations of every customer we serve. Through our sourcing and customer service you will know the product you are receiving is exactly what was advertised and will work to your specifications. You are purchasing genuine Times Microwave Cable. This is not a look-a-like or off brand cable. Please choose your desired length of cable in the variation section of the listing to support your project's needs. The connectors are a nickel, gold, steel tri-metal solder tip connection. LMR-400 has been the industry standard in RF cable for over 30 years. In the pictures section of the listing you will find the spec sheet for Times Microwave LMR-400. This is not the Ultra-flex version of LMR-400 so repeated bending will lessen the resilience of the cable. Please feel free to contact us with anything questions with this listing - we would be happy to assist you.
