Linear decoupling traps

Theory says that whatever condition exists at far end of 1/4 wave
stub will
appear at fed end. ie. if far end is left open a high impedance will
appear at fed end, at resonant freq. So it would appear that the
shorted end should be nearest
to feed point of antenna. The centre of dipole or bottom of a
vertical.
Hope that makes sense!................................Rod EI3CZ
You have it just backwards. A 1/4 wave stub is an impedance converter. i.e.
a short at one end appears as an open at the other end.
