yes, my hd dtv setup is SWM.. and the meter that comes from TV 4 RV is like the one in my photo up top, and i bet is a similar model to the one pictured by Gaspedler .. these will not work directly "in-line" with a SWM system, but they WILL work i am told by TV 4 RV if you use a splitter like the one that is in place in the photo Kevin & Jane posted above. Basically you attach a 2nd coax through the dish arm to the lnb, and as i understand splice the meter in the 2nd line to the zinwell splitter and power the meter with a seperate $10 power supply. A few more things, couple extra steps initially.. but might make aiming the dish easier
The trouble with just using the screen is unless you are REALLY close to where it needs to be aimed, you get no readings..
Kevin/Jane, do you have a separate receiver for each tv in your rig ? i assume so since i can see the splitter and the booster thing mounted in the basement area
