Bilge. All of it. A 66 foot dipole is roughly a *half wave* dipole on
40M and a 134 foot dipole is roughly a *half wave* dipole on 80M. A 33
foot long center-fed dipole is a quarter wavelength long on 40M but it
is not resonant on 40M and ya better not get stupid and feed it with
coax then just plug it into the back of yer radio if ya wanna work
anybody with it.


A search on google on quarter wave dipole will give plenty of sources.
