coils on mobile antennas

[coolbreeze]

back in the day the coil antenna was originally made so the big power guys could ride around and talk. On burbs or vans 102 drive around is not an option.
in the creation of many different coil antennas some have negative affect. to many coils or to tightly wound can result in a dummy load. also affect how they react with eachother in a 2 antenna set up.
why is one antenna design better then another. because of the inductance of the coil. or the capacitance created by the length of the bottom shaft. any by flat out testing, of which results coinsided with the mathmitical results.
