I think you're confused about how a choke-balun works. If I transmit 200W, the ferrite does not see this power. It only sees the fraction that tries to escape along the outer of the coax - this is ideally 0 if everything is working, but will be much less than 1 assuming a reasonable antenna. birmingham blitz volleyball tournament 2023
