Hi Bob!
I don't have any additional weight as a specific counterbalance, but I did mount my two X-Quads at their balance points.
So, while I was only as scientific as the "balance the antenna on your finger until it doesn't dip in either direction" method to find the center point, I feel like I am putting minimal stress on the elevation rotor.
Since my S-Band Wimo helical could not be mounted at just any point along its length, I did add a few inches of PVC to the bottom of the boom. Epoxied inside the PVC are a few fishing weights to cause the obvious mounting point on that antenna to also be the balance point.

Do a lot of you, or all, use a counterbalance weight on your elevation rotor? If so, how did you implement it?
I have 3 antennas (2M, 70cm, 23cm) on my cross boom and want to reduce the load on the Yaesu rotor so it lasts longer.
