Thanks Terry, Good idea. I'll hop over to RS tomorrow morning and pick up the termination and t-adapter if in their in stores. BTW, stumbled across a few old panel meters today (mainly for my input current replacement meter - found an 80A AC current meter, but needs shunt). I picked up the lot at 50 cents each. Most are low vdc type, but there is an RF current meter (to 120mA) and a db meter (-6 to +3bd). Just curious if anyones used a db meter in coil work? Take care, Bart "Terrell W.
