Anyone have a big Rogowski coil i can borrow. i need a 9 foot one and a 1 foot one for measuring tree currents. Also looking to buy an antenna coil. i need a fairly small coil. 2 to 3 inches in diameter that will handle 100W and load an 8 foot whip on 480 kHz. Many turns, maybe 5 mH, Lots of RF HV. Paul wa2xrm
