What is RG rating on coaxial cable?
What is RG rating on coaxial cable?
When referring to different types of coaxial cables, RG stands for “Radio Guide,” a designation derived from World War II military specifications. Each type of coaxial cable has a different RG rating to help distinguish the cables’ distinct characteristics and specifications.
What is RG 6 coax used for?
The RG-6 is primarily used for cable and satellite signal transmission for residential or commercial installations. This coax cable is thin and easy to bend for wall or ceiling installations and remains the preferred choice to relay cable television signals.
What does RG in RG6 stand for?
Radio Guide
“RG” means “Radio Guide” and was the original military specification for coax cable back in the thirties. You will probably have come across RG-6, as it is the industry standard for cable and satellite signal transmission. The RG-6 is a thin cable which is ideal when you need to coil or bend within a wall.
Should I use RG6 or RG59?
If you aren’t sure which cable to get, then RG6 cable is your best bet. RG59 cable is thinner and is recommended in low bandwidth and lower frequency applications such as analog video and CCTV installations.
Do I have RG6 or RG59?
You should avoid buying these coaxial cables. The other way to tell the difference between coax RG6 and RG59 cable is to compare their diameter. Normally, the outer diameter of RG6 is 6.90mm, while the RG59 is 6.15mm. RG6 cable is thicker than RG59 for it has a thicker center conductor.
Where is the balun on a coaxial cable antenna?
This antenna can use a coaxial cable feed and the balun is located right at the dipole element to ensure that the each side of the element receives equal currents and prevents external shield currents. The feedline should route straight away from the antenna center at right angles to the antenna conductor.
Is a 4-1 Balun a good choice for antenna tuners?
Based on the above, a 4:1 balun or any voltage-type balun is the wrong choice for use with antenna tuners in multi-band dipole systems. Most tuners use them because they are cheap, easy to build, and because almost everyone else uses them. For antenna tuners or systems with high SWR, we have a special balun.
What is the difference between DxE baluns and current baluns?
Current baluns can also be used as isolators or un-un’s. Unless otherwise noted, DXE Baluns are current-type baluns. Antenna systems requiring antenna tuners or matching networks often have very high voltages or currents on transmission lines and baluns, even at modest power. In many cases, voltage and current are not in phase with each other.
What is the best balun for this application?
The best balun for this application is a 1:1 ratio current balun. The part numbers of the correct 1:1 current baluns would be the DXE-BAL050-H05-A, DXE-BAL050-H10-A, or DXE-BAL050-H11-C, depending on power levels.
