Hi All,
JB's Handbook calls for 130ft of #20awg power wire and #23awg trigger. On the old Bedini monopole3 group the coil is 850 turns #23 power and #26 trigger.Yet I see a lot of people using 150ft #23awg. And even more people building machines with 130ft to 200ft#18awg.
I know that each machine can be built for a different purpose and they are all tuned with the right base resistances, matching transistors and diodes...etc
But all these different coils dimensions beg the question: What are the design trends?
#18awg is twice as thick as #23awg and has more then 3 times the cross section: Which means for the same length wire #18awg resistance is about 3.15 smaller then #23awg. But will coil with roughly half the numbers of turn on a spool. What criteria is most important when choosing a coil or wire size? Or does it all come down to the same thing at the end if the circuit is properly tuned.
Any thoughts?
