Winegard SensarPro wall plate problem
I have the SensarPro TV Signal Strength Meter (RFL-342) which has worked fine for a few years. Rushing back to Canada from Florida, we used it in a few places. Now that we're home in mandatory 14-day ...

11.6 is plenty. in addition to the coax loss you have between 0.1 and likely 1/2 volt loss in the switch. possibly more but I'm guessing 1/2 THIS IS A GUESS.
Now if the coax is not waterlogged there should be ZERO voltage loss in the coax when testing with a meter if there is any noticable difference between the jack on the Sensar Pro and the antenna end of the coax you have bad coax.
Why is this? VOltage loss is caused by resistance.. Since there is no load, (other than the very high impedance/resistance meter) there is effectively NO LOAD. and thus no current so if you were to take say a 10K ohm Resistor and hook one end to your 12.9 Volt source. You would measure 12.9 on the other end too. but if you added a small load you'd get next to nothing.
