Optional Booster Coils BCOI 9180-#W (#=Turns, available with 3, 4, or 5 turns)

The booster coils are used to generate the highest field strengths in conjunction with a high power balun (e.g. VHBD 9134-4 or VHBD 9134) and radiating elements (e.g. BBAL 9136 or BBAE 9179) in the frequency range from 20 MHz to approx. 60 MHz.
