I purchased a Winegard carryout G3 to use with my 2003 Adventurer .I am having a problem with the wiring from my DTV HR54 receiver to the 2003 RCA tv . The HR54 has hdmi port and the tv has rca ports. Is there a converter for this? Also do I need a power insert and multiswitch kit to make it work? Anybody have a drawing of the wiring for this hookup of one receiver. Thanks
