What is RG in coaxial cable?
What is RG in coaxial cable?
RG, or Radio Guide, is the original military specification for coaxial cables. Different types of RG ratings for each type of coax cable help to distinguish the distinct characteristics and specifications of the cable. For example, in the designation RG#/U, the U indicates general utility use.
What are some characteristic features of RG 59 Cabling specification?
RG-59/U is a specific type of coaxial cable, often used for low-power video and RF signal connections. The cable has a characteristic impedance of 75 ohms, and a capacitance of around 20pF/ft (60pF/m). The 75 ohm impedance matches a dipole antenna in free space.
What are the important characteristics of a cable?
Physical characteristics of acable basically include Physical Dimensions, Temperature Rating, Bend Radius, Flex Radius, Pulling Tension. Physical dimensions are diameters of the wire conductors, jackets.
What’s the difference between RG59 and RG6?
RG6 cable is heavier gauge and has insulation and shielding tuned for high-bandwidth, high-frequency applications such as Internet, Cable TV, and Satellite TV signals. RG59 cable is thinner and is recommended in low bandwidth and lower frequency applications such as analog video and CCTV installations.
What are the different RG cables?
Coaxial Cable Sizes
| Coaxial cable type | Outside diameter | Outside diameter |
|---|---|---|
| RG-58 | 4.95mm | 0.195″ |
| RG-59 | 6.15mm | 0.242″ |
| RG-6 | 6.90mm | 0.275″ |
| RG-62 | 6.15mm | 0.242″ |
What does RG mean on coaxial cable?
USA RG systems for coax cable types: The RG series was originally used to specify the types of coax cables for military use, and the specification took the form RG (RG from Radio Guide) plus two numbers. In some instances these numbers were followed by the letter U which indicated it was for multiple uses.
What are the characteristics of fungal fungi?
Fungi, like plants, are mostly sessile and seemingly rooted in place. They possess a stem-like structure similar to plants, as well as having a root-like fungal mycelium in the soil. In addition, their mode of nutrition was poorly understood.
How are RG400 cables tested?
The testing of the RG400 and other military coax cables are very rigorous and the specifications even more so. The RG 400 manufacturers are required to test attenuation and structural return loss by sweeping 22 different 50-ohm cables over the frequency band for which their use is recommended.
What is the difference between UR and RG cable type numbers?
One originated in the United Kingdom and its type numbers all start with UR. The other system is American with type numbers commencing with the letters RG. UK UR system for coax cable types: The UR system as defined in the UK and is still widely used for coaxial cable. UR standard for Uniradio, and later the URM series stands for Uniradio Metric.
