I cannot tell from your description what is your
exact configuration. Is this it? (fixed font)

Simple vertical monopoles should not be longer than
5/8WL.

Hi Cecil,

In your first reply you talked about 2x 5/8 wave with 0,2 wave in serie to
50 ohm.
That is the same as in your example here? Or must we use it al the way up to
my transciever? I am still talking about 5/8 wave for 2 meters.

No, my first reply was about a 2x5/8WL dipole fed in
the center with 0.2WL of ladder-line and no ground plane.

Or must we use it al the way up to
my transciever? I am still talking about 5/8 wave for 2 meters.

You can turn the 2x5/8WL center-fed dipole vertical
in which case, like a vertical center-fed 1/2WL dipole,
it doesn't need a ground plane.
