1.11 Coaxial Cable and Antenna Installation Tips
Avoid using 25’ of coax length if a 10’ will be sufficient.
Never use more than 25’ of RG-58 cable in any antenna installation
Always use shortest length of coax possible. Longer than necessary coax lengths
translates into greater signal loss.
Always use the straightest most direct routing possible in any coax installation.
Unnecessary and tight bends adds to potential signal loss.
Use 50 Ohm impedance coax only. Do not use 75 Ohm coax for the connection of
remote antenna. RG-8, 9913, LMR-400, LMR-600 and RG-58 are among a list of
acceptable 50 Ohm coax.
RG-59 and RG-6 are 75 Ohm and NOT to be used.
Use the proper coaxial connectors and crimp tool for the coax selected. Incorrect or
poorly installed connectors can have a significant effect of the performance of the RF.
