I am looking for information on how to build a W9INN 42' dipole that is
supossed to cover 10-15-20-40 meters. I understand that he is a silent key
and that his antennas worked great. Googled and found a lot of
information but nothing on measurments or how to build one.

Try an extended double zepp for 10 meters it works on 10-40 with a tuner .
