MP Enterprises claims extremely wideband receive coverage--25-6000 MHz (6 GHz)! For transmitting, it can accept up to 200 watts of RF power at 50 ohms impedance from 120-512 MHz, and 100 watts from 512-6000 MHz. VSWR averages 1.6:1-1.8:1 continuously through 6000 MHz.
Maximum height is 19 inches, with the top of the cluster of elements flaring out to a 12 inch diameter. Weight (less base) is a mere 5 ounces, yet the sturdy, stainless-steel elements, firmly locked in place with set screws, provide reliable ruggedness with their low wind load at high road speeds with strong magnetic-base with cable.
