What type of cable is commonly used for connecting antennas to wireless systems?
Coaxial cable
Coaxial cable, sometimes known as coax cable, is an electrical cable which transmits radio frequency (RF) signals from one point to another.
How far can I run a HD SDI signal over coax cable?
about 100 meters
HD-SDI is regularly transmitted over low-loss digital video grade RG6-style coaxial cable up to a nominal maximum distance of about 100 meters.
What cable do antennas use?
An RG6 coaxial cable is best used for connecting a TV set or set top box to a TV aerial, satellite dish or satellite receiver. It is also used for the internet and digital video. RG-6 cables are made with a different kind of shielding and have a 75-ohm impedance, making them more effective for carrying GHz signals.
How are unidirectional antennas used in Mic systems?
In wireless mic applications, unidirectional antennas are typically only employed in UHF systems. They tend to be frequency-specific, so some care must be taken in selecting the proper antenna to cover the required frequencies.
Where do you hang a wireless mic antenna?
When you’re setting up antennas, resist the urge to hang them at the end of a length of BNC cable in order to achieve line of sight. Wireless mic antennas are ground-plane antennas, which means they need to be attached to a ground source that is the same length as the antenna in order to work properly.
Do you need a ground source for a wireless mic?
Wireless mic antennas are ground-plane antennas, which means they need to be attached to a ground source that is the same length as the antenna in order to work properly. While it may seem as if RF acts like a spotlight or a fire hose, the reality is not so tidy.
Why do you need an antenna for a wireless microphone?
As we attempt to operate more wireless microphones in less spectrum (our legal range now falls between 470MHz and 600Mhz), proper application of antennas becomes very important. If you’re finding that your wireless microphones are suffering dropouts and noise bursts, optimizing your antenna usage and placement is the key to improving performance.
