Antenna length based on the following formulars:
1/2 λ dipole (feet)= 468 / frequency in Mhz.
1/2 λ dipole (meters) = 142.65 / frequency in Mhz
Full wave loop (feet) = 1005 / frequency in Mhz
Full wave loop (meters) = 306.32 / frequency in Mhz
Cut wire slightly longer for connecting insulators and pruning.
