Why the nitrogen?

Last time I had tires replaced the guy wanted me to have the tires filled with Nitrogen. Said I’d get better gas mileage and would prevent ingrown toenails.

He maintained that an antenna could be simply thought of as a transformer to bring the outputof the transmitter from 50 ohms to 377 ohms.  The biggest part of the antenna that is near the "magic 377 ohms" worksthe best.
