Default Gamma fed or folded dipoles?

I am going to build an array of 4 stacked dipoles for operation on 2 metres.
I would like to know whether the gamma fed dipole has any advantage over the
folded dipole, apart from the folded dipole being a tad more difficult to
make.

I have heard that the gamma fed dipole has a skewed radiation pattern in
comparison to the folded one.

Any thoughts and advice?
Many thanks


The Clemens match is a variant of the gamma match that gets round that
problem. I tried them on 6m and 4m.

You need to watch the losses in the coax dielectric. I vaporised UR67
and had to go to PTFE.
