can anybody explain the term "reflect from the body of the vehicle" ?,
people say it all the time including some
cb antenna builders, a typical claim would be "you must have your coil above the roof of the car or you get reflection from the roof"
i can see an increase in distributed capacitance between the radiator and vehicle, i can see an increase in capacitance shunting the coil, both of which would change the feedpoint impedance to some degree,
either could make the match between coax and feedpoint better or worse thus increasing or decreasing reflected power from the feedpoint but the term reflect from the roof/vehicle body i dont get at all,
what is this reflect many people talk about?.
