Cable Solutions is an Authorized Jensen Transformers Distributor, so our customers are ensured full warranty protection and technical support.Please click here to see them! Jensen Transformers' Description The VRD-1FF does not include any cables, but if you need them, we have some very high-performance RF cablesĪvailable. In order to insert the VRD-1FF into your signal path, and you may want to consider upgrading your existing cable(s)Īs well. You will need at least one short patch cable Good cables are very important in the fight against hum and noise. That one can install in an A/V system that can provide so much improvement with so little effort. Immediately, the effects of the ground loop become a non-issue. Just insert it anywhere in the RF line between The Jensen Transformers VRD-1FF is elegant in its simplicity. The result of this difference in ground potential is commonly referred to as a ground loop. Of other reasons that are beyond the scope of this article. One of the circuits is loaded more heavily than the other, or because one run is longer than the other, or any number Even when theĬode is properly observed, there are other factors that can cause a difference in ground potential. The National Electrical Code requires the cable system to beīonded to the power service entrance ground, but in actual practice, this is not always the case. The equipment that is used to enjoy the programming. In cable TV systems, the power supply for the cable system amplifiers are powered by a different source than The result is unwanted hum or video hum bars. When ground loops happen in a video system, Ground loops can happen even in the most carefully planned A/V system. It is a subject that is seldom discussed in manufacturers publications, or even in magazines of the trade, but Ground Loops? (or why the best planned systems sometimes look and sound bad) The VRD-1FF is made in the USA, is backed by the manufacturer's comprehensive one-year warranty,Īnd has a remarkable 20-year warranty on the transformer device itself. Over the world, we think it is a genuine treasure to find a company like Jensen Transformers, actually designingĪnd manufacturing some of the finest products in the world, right here in the USA, and we are proud to be able to Please do not confuse the VRD-1FF with similar (but inferior) products. If you're not sure which model to choose, please check out our Meets FCC Part 76 Regulations for CATV systems.Capacitive based design minimizes broadcast channel interference.Low VSWR helps prevent digital cable channel degradation. ![]() ![]() 2 MHz to 1300 MHz bandwidth spans VHF/FM/UHF/CATV spectrum.Improves audio/video quality by reducing 60 Hz ground currents.This is one case where "new and improved" is actually true. Thus preventing lost channels (as is so common with lesser devices). We have not found any other passive isolator that can so effectively solve ground loop issues, while also The overall length is 2.375 inches and diameter is 0.82 inches. Each end of the isolator has a machined 75 OHM female F connector with So often causes the infuriating audio hum or video hum bars we experience when connected to CATV. This improved ISO-MAX isolator has ruler-flat responses to over 1,300 MHz, making it suitable for digital cableĪs well as conventional CATV, VHF/UHF antenna or MATV systems. Path for radio frequency video and cable modem signals. It can prevent hum or buzz in sound systems as well as hum bars in video systems, while providing a transparent The elegant nickel-plated metal body complements the improved performance of what was already a class-leading product. Often the direct result of ground loops, so in that sense the ![]() VRD-1FF isolator uses a capacitive-based design to toĮlliminate AC power-related ground currents.
