Increased cable television tap bandwidth utilizing existing tap housings

1. A cable television tap comprising

a housing;

connectors to receive a main transmission line;

a tap plate in communication with the connectors, wherein the tap plate comprises a faceplate that includes RF circuitry to receive RF signals from the main transmission line, to provide a conduit for the RF signals to pass through the cable television tap, and to process the RF signals for communication with a customer;

a bypass line to provide an alternative conduit through the cable television tap when the tap plate is removed; and

a resonance restricting material disposed on the tap plate and adjacent to the bypass line when the tap plate is not removed,

wherein the resonance restricting material is disposed, when the tap plate is not removed, in electromagnetic communication with the bypass line such that the resonance restricting material reduces resonances generated by the bypass line and reduces insertion losses in RF range while the cable television tap is powered, and enables bandwidth for the cable television tap to be increased.

3. The cable television tap of claim 1 , wherein the resonance restricting material is a ferromagnetic material.

4. The cable television tap of claim 1 , wherein the resonance restricting material is a conductive elastomer that includes an elastomer binder and a conductive filler.

5. The cable television tap of claim 4 , wherein the elastomer binder is silicone and the conductive filler is a combination of nickel (Ni) and carbon (C).

6. The cable television tap of claim 1 , wherein the resonance restricting material has a rectangular cross-section.

7. The cable television tap of claim 1 , wherein the resonance restricting material has a U-shaped cross-section.

8. A cable television tap utilized in a cable television network to provide a connection point for a customer to access services provided by the cable television network, wherein the cable television tap includes a housing, connectors to secure to a main transmission line, a tap plate comprising a faceplate having circuitry to process RF signals to provide for communication with the customer, and the cable television tap further comprising a bypass line to provide an alternative conduit through the cable television tap when the tap plate is removed, wherein the bypass line generates resonances at a defined frequency in response to RF parameters in the cable television tap and the resonances increase insertion losses at the defined frequency and precludes bandwidth of the cable television tap being increased above the defined frequency, wherein an improvement comprises:

a resonance restricting material disposed on the tap plate and adjacent to the bypass line when the tap plate is not removed, wherein the resonance restricting material attenuates the resonances generated by the bypass line at the defined frequency and reduces the insertion losses at the defined frequency while the cable television tap is powered, and enables the bandwidth of the cable television tap to be increased without requiring the housing to be replaced.

9. The cable television tap of claim 8 , wherein the resonance restricting material restricts the resonances created at approximately 1.2 GHz.

10. The cable television tap of claim 8 , wherein the resonance restricting material enables the bandwidth of the cable television tap to be increased from 1.0 GHz to 1.8 GHz.

11. The cable television tap of claim 8 , wherein the resonance restricting material is an EMI shielding material having lossy characteristics in range of the defined frequency.

12. The cable television tap of claim 8 , wherein the resonance restricting material is a conductive elastomer that includes an elastomer binder and a conductive filler.

13. The cable television tap of claim 12 , wherein the elastomer binder is silicone and the conductive filler is a combination of nickel (Ni) and carbon (C).

14. The cable television tap of claim 8 , wherein the resonance restricting material has a rectangular cross-section.

removing the tap plate, having a resonance restricting material disposed thereon and adjacent to a bypass line for the cable television tap, from the cable television tap;

performing maintenance on the cable television tap; and

installing the tap plate on the cable television tap, whereby the resonance restricting material is disposed, when the tap plate is not removed, in electromagnetic communication with the bypass line such that the resonance restricting material attenuates resonances generated by the bypass line at a defined frequency and reduces the insertion losses at the defined frequency while the cable television tap is powered, and enables the bandwidth of the cable television tap to be increased above the defined frequency.

17. The cable television tap of claim 1 wherein a space is located between the bypass line and the resonance restricting material.

18. The cable television tap of claim 8 wherein a space is located between the bypass line and the resonance restricting material.

19. The method of claim 16 wherein a space is located between the bypass line and the resonance restricting material.
