Does anybody have any experience with a 3 element SteppIr yagi in -40C weather?
I want to have a beam I can put up and leave alone.

Coldest I've ever operated my SteppIR 3L, and BigIR is -25C, but that's about as cold as it ever gets here.  Both functioned as if it were 32C outside.  Both have been deployed for several years now and have required no maintenance whatsoever.

I've had a 3L SteppIR with the 40m element for several years here in Minnesota. I've had no problems at all at temperatures down to below -20 F. I have had my HAM-4 rotator stop functioning until it warmed up a bit, but the SteppIR has been flawless.
