No. See my post in this thread about resonance.

BTW -- I strongly agree that clamp-ons should be secured with a ty-wrap. 
And something I missed the first time around, but corrected in the 
latest version of RFI-Ham is that turns must go though the core in 
sequence. Out of sequence turns cancel in-sequence turns. Learned this 
from some measurements.
