This antenna extension cable works on all XM Radios using a FAKRA connection. Easily extend your original Delphi SKYFi, SKYFi2, or XM Radio add-on antenna length.You may experience slight loss of signal reception since there is no amplifier to counter the minor signal loss that the added cable length causes. DO NOT use more than one of these 25' extension cables in any antenna extension configuration. To disconnect the cable, grasp the gold connector only. Pulling on the cable itself could cause internal damage.
