How to calculate RF signal loss in coaxial antenna cable

Date Updated: September 14, 2017
Question:
Is there an easy way to calculate the loss of RF signal as it travels over coax cable? I think this is important when installing remote antennas for wireless mics.
Answer:


Indeed it is important.
Shure has a remote antenna tool to help determine which cables and amplifiers to use at: Wireless Mic Remote Antenna Tool
Here is an online calculator for cable loss: http://www.timesmicrowave.com/calculator/
