The standard antenna has coverage at 6 meters, but space is not optimal, so performance similar to a high gain dipole - gain of 5.0 dBi, but only 2 dB from front to back. Add the 6 meter passive element kit that gives 3 elements very well spaced with gain of 8.3dBi and front to back of 20 dB. Because this is a fixed element, the performance effect is only good from 50.0MHz to 50.300MHz. A must option for anyone using 6m!
