Remember the ant switch is getting power when either the House battery is in USE; or when Chassis Battery is ON. If either is OFF the LED light stays on. If both are OFF the LED light goes out. The same is true to turn Inverter on. If Inverter is ON then everything on Inverter circuit has power even though USE/STORE is in STORE mode.
The LED is a trivial load; not sure about the antenna pre-amp, but likely small as well.......it would be nice to have a schematic for the specific wiring. At least you can either turn off the ant switch when not in use, or disconnect both battery strings to kill it as required.

Yes both workarounds work. For kicks I was gonna try to see how low the draw was for the LED / pre amp only (using my digital readout in hundreds of KWs from inverter; so I purposely make sure Chassis is ON and USE/STORE in Store mode. And the LED light did NOT come on!!! So I press wall plate button thinking making I had the switch on cable, but it stayed dark. I then go to the Inverter remote and try to turn it on and it does not come on!!! So at that moment everything appeared to be working. I switched to USE mode and the LED came on and I was able to turn on Inverter.
However, when I turned the USE back off; the LED for ant stayed on, and I was able to turn on Inverter again
This was about 2 hours after the Test above in previous post. I don't know if this is repeatable? I may try to start it again with the Chassis battery disconnected to see ?
I agree the LED & Pre amp is likely not pulling enough to worry about, but I am very curious now. I also have to account for the fact that if I do got to store mode and inadvertently left the the inverter on, I could be drawing who knows what on the inverter circuit? I don't think the latter will happen because we don't leave the inverter switch on even though it will switch automatically.
