    Better that trying to use RFI

    I was having trouble with XM radio on our car and kept having problems with finding unused radio channels, so we had this installed with a new XM receiver to inject a signal into the FM input on the radio. It has worked great for the entire time we have had it and we have no more problems traveling and getting a clear XM signal. This item was part of an installation and there was also a receiver and installation, but it was SO worth it. There is no pic, but you don't see it anyway.

    Required for our XM install

    We can't see it, but apparently it's there. Needed to install XM Onyx radio with car kit. Makes my wife happy to have a clear radio signal on XM.

    Not sure about this other than it is a required piece to make the rest of the antenna adapter work. It works great!!

This crossover adapter converts any standard Ethernet cable to a crossover cable. Network two computers together without a hub, or join two hubs together without the need for a "crossover" cable. Great for starting a home network.
