I used to have a 25 element beam for 2 meters, way overkill since at the
time I actually did want to get on the band, and even that was not heavy. I
had it on a real light rotor and it had no problem. I could hole that beam
up when I put it up one handed while mounting it with the other hand, that's
how light it was so I can't imagine one less than half that size would need
much.
