The 6M Option is a perfect add-on for the W4OP Loop. The 6M system behaves more like a quad loop — broadbanded and gain about equal to a dipole. Maximum radiation is now perpendicular to the plane of the loop. One full rotation of the variable cap is only 800kHz on 6M, making tuning extremely simple. Maximum radiation is at right angles to the loop as would be expected with a larger circumference loop (in terms of wavelength).
