I use a square wooden dowel on the back end of my Arrow that I clip my RX radio on to act as a counter balance.

Hasan, front to back on the EL so as to reduce the load on the motor and gears.
thanks,

Bob, Are you talking Front to Back (EL) or Side to Side ?
When I had clearance issues I had to mount my 2m yagi forward of its natural balance point. I hose clamped a steel bar on top and parallel to the boom to rebalance the load of the yagi on the rotor. It worked fine.
I
also used tape protected tie-wraps as a secondary safety net, so the iron bar didn't fall on someone's head!
I did not have any side to side balance issues across the rotor. (The
70cm
on one side and the 2m on the other, but if I would have, I would have
used
the same trick: Steel bar on the lighter side of the boom, to balance the load across the rotor.)
Cheap, easy, dirty. But be sure to make that steel bar counterweight
mount
to the antenna boom or cross-boom VERY secure.

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.
