JSC Wire RG-58A/U Shielded Coaxial Cable 100 ft. USA
is this the correct cable for remote set up of a wireless microphone 1/2 wave antenna?
First, the world of RF mics can be an annoying, flaky one. Little techie things can mean the difference between a great event and preferring to be dead. Skimp on speaker cable before you skimp on coax for your wireless mics.Second, the best bet is to check w/ tech support at the maker of your system. Describe your plan and ask the tech for recommendations. Ask them to recommend particular brands and part numbers. The system is their product. They want you to show it in it's best light. They will impart wisdom.In all likelihood, this cable would work OK for distances up to 15 feet / 5meters ( +/-???)The issues that come into play are...-What is the impedance (50, 75 Ohm or other) of the receiver and of the antenna? It can be very important to use cable appropriate to the impedance of the system components, particularly at higher frequencies and/or longer distances. I'm pretty sure that RG58 is a 50 Ohm cable. Most wireless mics stuff that I've bumped into is 50 Ohm.-At what frequencies do your systems operate? The higher the frequency, the more important the cable quality.-How long will your cable runs be? Longer runs will likely require better cable.-How "bomb-proof" do you need your system to be?In any event, I would NOT use the cheapest cable that barely does the job, particularly if I'm using the system to earn a living. The RF microphone scene is just too chaotic to justify use of marginal stuff.
