Hello Ted,
You didn't mention whether you had an ARR pre amp with the RF sensing.
I have been using my ARR pre amp for 15+ years outside (with a cover). I open it every year or two and the inside still gleams. The exposed toggle switch is showing its age though. My recommendation is to get the pre amp with the RF sensing. My opinion is that there is no if you will inadvertantly transmit through it, just when.

I just sent my ARR pre amp back to ARR for repair for the 3rd time !
(pretty sure I did not tx through it )
What are people using for pre amps. I only see the Mirage as an alternative. Any other choices. I'm kind of disappointed in ARR products. Is there a pre amp that you can tx through preventing accidental frying?
Any thoughts appreciated
