External SXM radio antenna for KW T680

The easiest solution is to use a quality 3M exterior automotive trim tape (2 sided stick) and affix a puck style antenna to the top of the driver side mirror and run the coax behind the mirror, and along the mirror arm with black tape or other means, and inside the door jamb.

This will stand up to washes and high wind if done properly.

 

Some of the xm receiver packages come with a “puck style” antenna and about 15 feet of coax lead.

 

For around 30 dollars on Amazon you can get a kit where you just pull sxm out of one vehicle and put in another.
Come with, mount, puck antenna, auxiliary connect cord, and power cord.
I pull my box from semi, then snap in truck when I am off.
Portable system from sxm as all this with service, then hardware kit from Amazon for the otherguys vehicle.

 

In my pick up, I just taped to inside dash, works great, semi like above op said, never have an issue.

 

If you work in the southwestern USA you can sometimes get away with positioning the puck on the dash somewhere but the further north and east you operate, the less effective this will be. At the very least it needs to be kept mostly level (horizontal) and be able to see as much sky as possible.

In my experience, the low profile pucks worked as good as the much more expensive styles that require a bracket or arm to mount.

 

Xez1v1 onyx ez model for complete kit.

Don't get the one that goes in cig dc plug, tends to bounce out a lot.
It only has a wire for antenna, blue tooth to radio and loses signal a lot.

 

Oh, one more thing. Make sure your truck radio has the audio connect port or you will need to get cig dc outlet style.
