Sirius XM Radio 50 ft Antenna Extension Kit with RG6 - Universal Fit

In this review of the Sirius XM Radio 50 ft Antenna Extension Kit the bottom line is simple: this kit is for anyone who needs a reliable, long run from a home, vehicle or amplified satellite antenna to a Sirius or XM receiver. The reviewer found the kit delivers practical value because it converts between common satellite connectors and RG-6 coax while providing a full 50 ft of cable, so receivers can sit where they are most convenient without losing a usable signal. It is a straightforward solution for radio setups that require extra reach.

Key Features

• Universal compatibility: Works with most Sirius and XM receivers when used with a home or vehicle cradle, enabling easy integration with existing gear.
• Complete connector kit: Includes fittings to convert from Sirius or XM antenna to RG-6 and back from RG-6 to SMB so the antenna port can be reached without splicing.
• Long 50 ft run: Provides a full 50 ft of RG-6 coax to position the receiver or cradle away from the antenna location for better placement flexibility.
• Multiple antenna uses: Designed for home, car, marine, truck or commercial amplified antennas, making it adaptable to several installation environments.
• Expandable with caution: Additional RG-6 cable can be added to extend length further, though an inline amplifier may be needed to maintain signal strength.

Who It's For

The kit is ideal for users who already own a Sirius or XM receiver and need to relocate the unit or cradle away from the antenna, such as placing a docked receiver on a shelf while the antenna stays mounted on a roof or window. It also suits mobile or marine users who want a neater, longer coax run to an external antenna.

Users who should look elsewhere include owners of boombox-style receivers with protective plastic covers around the antenna port, since the included connector for the cable may not fit those models. Also, very long multi-cable installations that demand amplified signal should plan to add an inline amplifier.

Pros & Cons

Pros

• Provides a convenient 50 ft RG-6 run that improves placement options for receivers.
• Includes the needed converters to go from Sirius/XM to RG-6 and from RG-6 to SMB, reducing guesswork in installations.
• Works with a wide range of antennas and receiver cradle setups for versatile use.

Cons

• The cable connector will not fit some boomboxes that have a plastic cover over the antenna port.
• Extending beyond 50 ft may require an inline amplifier to preserve signal strength.

Specifications

Our Verdict

The Sirius XM 50 ft Antenna Extension Kit is a practical, low-friction way to extend satellite radio receivers away from their antenna location. It offers good value for owners who need a tidy 50 ft RG-6 run with the correct adapters included, and it avoids unnecessary purchases for most home and vehicle cradle setups. Those with boomboxes that have covered ports or who require very long runs should plan for compatibility checks or an inline amplifier.

Frequently Asked Questions

Will this kit work with my Sirius or XM receiver?
Yes, it works with most Sirius and XM receivers when the receiver is used with a home or vehicle cradle; check that the receiver antenna port is accessible for the included connector.

Can the cable be extended beyond 50 ft?
Additional RG-6 can be used to extend the run, but an inline amplifier may be needed to maintain desired signal strength for longer distances.

Will it fit boombox-style radios?
The connector for the cable will not work with some boomboxes that have a plastic cover around the antenna port, so verify port access first.
