This kit allows for multiple receivers to be connected to one XM Radio antenna. This kit, when used with the appropriate antenna, can be run to cable lengths less than 75 feet. This kit provides the flexibility to allow the installer to cut RG-6 cable to shorter custom lengths and to use plenum rated RG-6 cable where fire codes require. A 3 foot length of small diameter coaxial cable is supplied with SMB plugs to mate with the radio and an S-band rated line amp. This is the easiest way to connect 1 antenna to 2 receivers for shorter cable run installs.
