Sirius 50-foot Antenna Extension Cable

Product Research

Features

Overview: The SIR-EXT50 is a 50' extension cable with an in-line amplifier for use with Sirius antennas; the kit is not compatible with XM satellite radio antennas. It can be used for Sirius mobile or home receivers.

Cable and Connector: The SIR-EXT50 antenna extension cable is a single 50' coaxial cable with single SMB connectors (without the plastic FAKRA-type plastic housing) on each end. The extension cable is equipped an in-line signal amplifier (10dB gain) on one end with a weather-resistant rubber boot. The other end plugs directly into single-input Sirius Satellite Radio receivers.

Extension Limits: No more than 2 extension kits should be connected back-to-back.

Cable Care: The full length of the extension cable should be used--it should not be cut, spliced or otherwise shortened. The cable should not be kinked. You should avoid bending the cable in a radius of less than an inch. The cable can be used outdoors, but it should not be exposed to severe environmental conditions. The in-line signal amplifier should be mounted upright, oriented so the label is readable right side up.

Specifications:

Cable Type: RG-58
Cable Length: 50'
Frequency: 2300 to 2400 MHz
Amplifier Gain: 10dB +/- 1dB @ 2300 MHz
Return Loss: -10dB
Connectors: SMB

Can I use this 50ft extension with a Sirius truck antenna tram 7732 will all the connections fit?

[ West Jun 02, 2019 ]

2 answers

You should be able to use it as long as your existing XM gear uses the SMB connector that is standard - this extension uses it on both ends.

[ Cosmo Jun 11, 2019 ] Staff

Not sure. After my purchase directions say I needed a RG-6 to mate my cables. Could be the same for you.

[ Santa Jun 10, 2019 ]

Will this work on my xm delphi radio boom box?.The current 20 foot antenna doesn't go far enough to clear metal roof and be able to point southeast to pick up satellite signal.

[ Clayton Dec 13, 2017 ]

2 answers

Yes, the connection fits.

[ Terry W. Dec 13, 2017 ]

Yes. Not a problem.

[ Johnny Dec 13, 2017 ]

Can you use 2 or 3 extension cables together ? I need to place the antenna about 125 to 135 ft from the Sirius receiver. Is that too far to get reception from the antenna?

[ greg Jan 16, 2016 ]

2 answers

No that's not too far. I ran my extensions 100 feet and have no problems with reception

[ Philip Jan 17, 2016 ]

have only used one but don't see why extension wouldn't; work

[ William Jan 16, 2016 ]

[ KEVIN Aug 03, 2015 ]

Can I use this on a Sirius XM radio that is installed in my 18 WHEELER?

[ Jerry Jun 08, 2015 ]

2 answers

Yes!

[ Jim Jun 09, 2015 ]

Hello Jerry It should/will work. It is just an extension of the short cord you get from Sirius. About 30 feet of mine is outside. The connector is water proof. This should allow you to get your tunes in your rig. Enjoy. Safe travels. Mike

[ Michael Jun 08, 2015 ]

Will this work with my SiriusXM SXV300V1 Tuner? I don't understand the square part

[ Jay May 05, 2015 ]

2 answers

YEs. The large end is a weather resistant cover for the plug.

[ FRANK May 06, 2015 ]

Hello Jay That had me concerned also. However it is a safety feature. It keeps the connection from coming lose and even adds a cover over the connection. It caused no problems. Mike

Pretty straight forward, plugs in between the antenna lead and your receiver.

[ KEVIN Aug 26, 2014 ]

Yes, In my application the smaller end of this cable went into the Sirius SXV200V1 tuner, and the larger end I connected to my car's factory Sirius antenna.

[ Nick Aug 26, 2014 ]

It's just like an extension cord. One end is male and the other has a female end inside of that large plastic thing. To conserve space I removed the big plastic cover from around the female end and then covered the connection with shrink tubing.

[ Donald Aug 26, 2014 ]

Hi Wayne, The 50 foot extension cable is really easy to apply. There are many applications that you can use: For example some people bury the cable underground some simply tuck it under the house siding if applicable. One side connects to the antenna port on the radio back the other side to the antenna itself. Don't be afraid to tackle it. Make sure the antenna is pointed correctly using the signal strength meter on your Sirius Radio and have someone spot you on the ladder... Enjoy the Music! Bob
