I have the 17’ Chameleon SS whip and am interested in using it for 6m SSB. The mfg. says that it can be used without a coil out to 20m. Has anyone had any experience with that antenna with no coil? Particularly how you tuned it and grounding.
Assuming this is the same 17’ telescoping whip as on the Chameleon MPAS Lite, the answer is yes.
Normally, I mount the whip and matching transformer on the supplied ground spike when hillwalking for SOTA. But on this occasion, I parked my estate car [station wagon] by the side of the road at a hilly location, I mounted the whip and transformer on a large HF magmount on the car roof. In this case the car provided the ground plane.
I was running 5W CW on 6m from my 20-year-old FT817 via a LDG Z11 Pro II ATU. I was getting and giving good reports from all over EU. No coil.
I’ve used the MPAS Lite much more often on 30m to 10m [no coil] [10W CW from KX2/internal ATU] with good reports. I use about 8m (~25ft) of counterpoise wire. I’ve found performance on 40m [again, no coil] is poor to adequate.
It is easy to use without the coil, it’s a simple vertical antenna. Use at least one counterpoise which can be attached the mount for the whip. Extend the whip to 1/4 wave - 54 inches for 6M - and tune by adjusting whip length. MFJ sells a mount, as do other manufacturers, for ~$20 or less for this purpose, MFJ-342T. Drive a 3/8" spike (12’ length preferred) into the ground, attach the mount and whip & counterpoise and you are all set to go.
