I have a 5th wheel camper that I carry along a portable dish on a tripod. I have rigged it with a Phase III dish and SL3 LNB for 99, 101 & 103 sat. It is hooked to a H21 to a HDTV. When I only used an 18" dish was not a real hastle to go to the door and look at the signal meters while aligning. But now will be going back and forth quite a bit while aligning 99 & 103. I do not have a signal meter so I am trying to come up with a better solution Do you think this will work? I have a 19" LCD PC monitor not being used with DVI input. I am thinking of buying a 35' HDMI-DVI cable from Monoprice ($25.00) and run that from the H21 to the monitor during dish alignment. I can then have a monitor outside while aligning dish and only have to go back in while changing sats. When finished aligning dish unplug HDMI-DVI to monitor and hookup TV to H21 with short HDMI cable.
