I have run into this problem with tower lighting controllers.
In Washington State, there is an option to install equipment which is not UL listed if you have one of the state approved Professional Engineers inspect the equipment,
issue a report and apply their sticker. Last I checked, there were maybe 10 individuals approved by the state to do the inspections. Cost was about $1000 for a tower lighting controller. 3 hour drive out, 10 minutes on site, then 3 hour drive back. Guy
seemed to enjoy the day away from the desk.
Most of my transmitter installs have had their electrical signed off without any problems. One inspector did question the Nautel NV10lt, I was able to show him
some info Terry Ellis of Nautel sent me (individual power supplies were UL listed, transmitter did comply with IEC…), then he signed off.

When you have installed a new transmitter and have a local inspector ask for you UL sticker or certificate on your transmitter, how did you handle this?
What did you give your local inspector?
We gave our inspector a letter from Nautel, and said he would send it off to UL.
