Whipless means they don't look like antennas, attract less attention, less vandalism, and have lower wind resistance. Field diversity makes the antenna resistant to the picket-fence fading and multipath nulls that are found in urban operation and undulating mobile environments. Versatile: Excellent for voice or telemetry applications Field Diversity: Field diversity means that the antenna is simultaneously sensitive to both the electric and magnetic fields of the signal, like having two antennas. 33 CM Band Amateur and Commercial communication supported
