I have one of those MFJ telescoping whips that extends to 1/4 wave on 20 meters (40 with a coil). Instead of cutting a bunch of quarter wave radials for each band I'm going to press into service an SGC290 at the feedpoint and use 16, 30 foot radials instead. When using the tuner should I still "tune" the whip to my operating band or just leave it fully extended? In other words is a resonant vertical more efficient then a non resonant vertical with the same SGC and radials in place? Thanks!

Are you going to use them as raised radials or just lay them on the ground?
If you are using them as ground radials, just lay 4-6 25FT (or there abouts) radials on the ground. Ground radials just are not resonant. Or should I say that their apparent resonance changes with what they are laying on.

Forgot to mention radials on the ground...
