Counter weight for antennas
In order to use back mounted antennas, it is necessary to use counter-balance weights (not wear the gear box of the rotator).
An idea is to use weights that is used for training ( it costs ~ 2Ε).
This weight can be mounted in a square aluminum profile 15x15 mm, the inner hole of weight is D28mm.
It used a M5 hex nut DIN934 and M5 screw DIN912 L12 stainless steel.
