What is the approximate length for a 1/2 wave dipole antenna cut for 14.250 MHz?
8 feet
16 feet
24 feet
33 feet✓پاسخ درست
توضیح
The standard approximation for a half-wave wire dipole is 468/f in feet with f in MHz, and 468/14.250 = 32.8 feet, which rounds to 33. The 16 foot choice is the quarter-wave length, 234/14.250 = 16.4 feet.
