Jensen Transformers VRD-1FF

ISO-MAX Cable TV Ground Isolator

Made in the USA
Jensen Transformers VRD-1FF ISO-MAX Cable TV Ground Isolator

Jensen Transformers VRD-1FF ISO-MAX Cable TV Ground Isolator

The Jensen Transformers
VRD-1FF is a capacitive-based isolator that provides a high impedance barrier to AC power-related ground currents. It can prevent hum or buzz in sound systems as well as hum bars in video systems, while providing a transparent path for radio frequency video and cable modem signals.

The improved capacitive isolator has ruler-flat responses to over 1,300 MHz, making it suitable for digital cable as well as conventional CATV, VHF/UHF antenna or MATV systems. The unit breaks that infuriating ground loop that so often causes the audio hum or video hum bars we experience then connected to CATV. Each end of the isolator is a gold-plated 75 OHM machined female F connector with an overall length is 2.375 inches and a diameter of 0.82 inches.

Here are the specifications:

  • Improves audio/video quality by reducing 60 Hz ground currents
  • 2 MHz to 1300 MHz bandwidth spans VHF/FM/UHF/CATV spectrum
  • Low VSWR helps prevent digital cable channel degradation
  • Capacitive based design minimizes broadcast channel interference
  • Meets FCC Part 76 Regulations for CATV systems

Please do not confuse the VRD-1FF with similar (but inferior) products. With inferior products coming from all over the world, we think it is a genuine treasure to find a company like Jensen Transformers, actually designing and manufacturing some of the finest products in the world, right here in the USA, and we are proud to be able to offer their products. The VRD-1FF is made in the USA, is backed by the manufacturer's comprehensive one-year warranty, and has a remarkable 20-year warranty on the transformer device itself.

Ground Loops?

(or why the best planned systems sometimes look and sound bad)

It is a subject that is seldom discussed in manufacturers publications, or even in magazines of the trade, but ground loops can happen even in the most carefully planned A/V system. When ground loops happen in a video system, the result is unwanted hum or video hum bars.

In cable TV systems, the power supply for the cable system amplifiers are powered by a different source than the equipment that is used to enjoy the programming. The National Electrical Code requires the cable system to be bonded to the power service entrance ground, but in actual practice, this is not always the case. Even when the code is properly observed, there are other factors that can cause a difference in ground potential. It can be because one of the circuits is loaded more heavily than the other, or because one run is longer than the other, or any number of other reasons that are beyond the scope of this article.

The result of this difference in ground potential is commonly referred to as a ground loop.

The Solution

The Jensen Transformers VRD-1FF is elegant in its simplicity. Just insert it anywhere in the RF line between the cable TV jack and your equipment.

Immediately, the effects of the ground loop become a non-issue. Problem solved. There are not too many things that one can install in an A/V system that can provide so much improvement with so little effort.

Don't Forget the Cables!

Good cables are very important in the fight against hum and noise. You will need at least one short patch cable in order to insert the VRD-1FF into your signal path, and you may want to consider upgrading your existing cable(s) as well. The VRD-1FF does not include any cables, but if you need them, we have some very high-performance RF cables available. Please click here to see them!

Shipping/Handling

USA Customers

Our standard shipping method for this item is USPS Priority Mail, an air service that provides one to three day delivery to USA addresses.  This service includes Delivery Confirmation and basic tracking information.

If you need faster delivery and better tracking, we also offer Express Mail, which provides overnight delivery to most (but not all) USA addresses.

For items weighing less than 13 ounces and valued at under $200, we also offer First Class Mail.  Transit times for this economy service are typically a day slower than Priority Mail and no tracking information at all is included.

For items weighing more than 13 ounces, we offer FedEx Ground.  Please click here for transit time to your area.  This service offers the lowest cost for heavier items and includes full tracking information.

Please notice that eBay's shipping calculator does not include FedEx services, but we will actually ship via FedEx at the UPS rates shown by the calculator.  For all FedEx shipments totaling over $200.00, a signature will be required upon delivery.  No exceptions please.

Please refer to the Shipping and payments tab to see actual available services and calculated rates.

International Customers

Our preferred international shipping method is Express Mail International (EMS).

For items under $300 in value, we also offer Priority Mail International.  Cost is somewhat lower, but you need to be aware that this service provides only minimal tracking information.

We insure all international shipments, but you should be aware that the insurance company requires a 45 to 60-day waiting period before a claim can be filed and tracking information can be comforting when packages do not arrive within the expected timeframe.

Please refer to the Shipping and payments tab for calculated rates and transit times to your country.

Keep in mind that these transit time estimates are from the US Postal Service. Circumstances in your country, such as delays at your local customs office, can affect the total transit time to your address.

International customers should be prepared to pay import taxes and/or duties at the time of delivery. In NAFTA member countries, customs duties should be discounted for products that are made in the USA, but taxes may still be collected.  Please be advised that we declare actual contents, value and country of origin for customs and insurance purposes.  No exceptions please.
