Description

Genuine U.S. Made LMR-400 Coaxial cable should not be confused with the imitations sold calling themselves LMR400 in most website listings. There ARE other quality coax producers out there other than Times Microwave. We sell a couple ourselves, but please - if you don't buy here do your homework. Certain Chinese plants make cable for a large number of resellers and as copper prices go up, the quality of the alloy used tends to go down as cheaper producers tend to substitute inferior alloy without telling or use cable with variable dielectric thickness and copper alloys less than 95% pure for poor conductivity.

Signal losses are frequency dependent! Don't bother buying a good antenna if you are running cheap cable. Losses can be reduced by increasing the diameter of the cable. A cable with twice the diameter will have half the signal effect resistance loss. Assuming cable quality is equal, the larger cable would halve the dB/meter loss. In designing a system, consider not only the loss in the cable, but also the loss in the connectors. Cheap connectors give you as much loss as cheap cable. On a final note, poorly made LMR600 "type" cable can have a greater signal loss than good LMR400.

This is Top Quality LMR400 50 Ohm Cable. All common Radio Frequency (RF) devices CB, Ham, WiFi, Packet Radio, etc. are to be used with 50 Ohm cables and connectors. 75 Ohm cables and connectors are designed for low frequency signals like Video or Cable TV and are unsuitable for most all RF installations. We have LMR-400 75 ohm for antenna matching if needed.

LMR-400 cable is designed for outdoor or indoor applications, can be direct buried, and the outer jacket resists ultraviolet light and oxidation. There is no environmental restriction on use for indoor installations.
