This is precisely why I put up the antenna that I did for 2M contesting. It
is a four stack of 3 element yagis. It analyzes to have 14.6 dBi of gain
with a 60 degree horizontal beamwidth to the -3 dB points. And it's really
not that hard to construct if you already have an HF yagi with a decent boom
on top of your tower- just attach the middle of the stacking mast out on the
HF boom a foot or so and end mount the yagis.
And, if there is some ice, I think having 4 driven elements will retain a
better match and pattern than if there was only one with a lot of sensitive
parasitic ones.

This can be summed up with "highly directional antennas". On HF, for
instance in SS, if I call CQ with a dipole, a good part of the target
audience is going to hear me. Even with a beam, if I'm pointed toward the
southwest, a large part of the country will hear me.
VHF+ beams/dishes have such so narrow patterns that it doesn't work this
way. Unless they're both running lots of power, both stations have to be
pointed toward each other to make a QSO.
