Works fine for receive. Don't know the math to predict the transmit wattage it might tolerate. Besides, an air variable used outdoors will have to be protected from rain and condensation. Got an enormous air variable I need to unload that has 5/8-inch spacing. Never did find a practical use for it. I was told it came from the tuning shack at the base of a AM-broadcast tower.

Probably time to post it on fleabay.

Air variable? Running barefoot? John said a 15kV vacuum variable barely handles an 8-pill, not sure air is the way to go there.

Yes, just have my analyzer connected to it. No need to put a radio on it until the antenna is right. Its an air variable like out of a Ham tube amp. Use that then measure its capacitance so its quicker with the vacuum variable. Air is just for tunning with the analyzer, Rig Expert AA-650 ZOOM.
