Join us for our next livestream event, understanding unity gain is an important concept that applies to the forward and reverse paths of most cable networks. Without it, network performance can be degraded. In this episode, Brady Volpe and Ron Hranac will walk you through the principles and practices of unity gain, what it is, and the importance of managing it in our networks. The goal of unity gain is to maintain the same signal strength from the headend (the central distribution point) all the way to

Very big and very small numbers

Mia Colabrese2024-08-14T11:02:10-04:00August 14th, 2024|

RF with Ron and Brady - This topic is a little different than previous presentations, but is important considering the widespread use of very big and very small numbers in cable. Ours is a world of numbers, and in cable we tend to use a lot of really big and really small numbers. In reality, it’s hard to grasp just how big or small numbers can be. Examples include the speed of light (a very big number) and RF signal levels in millivolts or microvolts, or even nanowatts

Coaxial Cable Impedance, Attenuation and Beyond

Mia Colabrese2024-06-13T09:40:50-04:00June 13th, 2024|

Some people say coax but Ron likes coaxial cable. Coaxial cable has been a key component in our networks dating back to the industry's early days. As such, it's easy to take coax for granted without really understanding just what it is. Here's your chance to learn more about coaxial cable, along with a high-level look at some of its characteristics such as impedance, attenuation, velocity of propagation, DC loop resistance, and more. Please tell us your thoughts in the comments. Coax or Coaxial? 📡 --- Ron's Bio:
