I could place it at 14.2 but 14.2 would be my desired operating freq!<< I would not rely on TOM, W8JI "wisdom," tune it to where it gives maximum signal and the best performance. Tom is way off and wrong on the subject of current in loading coils on the antenna. He has extensive article on his web site that is completely wrong, there was quite a discussion on eHam.net and rec.radio.amateur.antenna newsgroup on this subject and people that measure things concluded that the current is not equal at both ends of the loading coil, while he is still insisting that it is (based on wrong assumptions and calculations). Since the trap is acting as a loading coil, looks like you stumbled on another proof that he is wrong and disseminating fallacy (not the first time). The final proof is in the signal strength and what you measure, not what someone "calculates." Looks like this business of current distribution in the loading coils has also significant impact on traps, which become loading coils at lower bands and knowing what is really happening will help to optimize them for better efficiency.
