Hello All,
I have seen shortened, center-fed, coil-loaded dipoles. These otherwise ordinary center-fed dipoles have a loading coil at the base of each leg.
(For example, a shortened 160 meter band dipole with 50 foot legs needs a ~70 microhenry loading coil at the base of each leg to bring it to resonance at 1.9 MHz.)
For an end-fed, stealthy version of this dipole (with a single loading coil in the middle of the 100 foot long continuous wire and hidden in a tree), what value should the center loading coil be to bring the antenna to 1/2 wavelength resonance? Should the loading coil value be twice the value (~140 microhenries) of the coils at the base of each leg of the center-fed version?
Many thanks in advance to anyone who can help. -- Jason
