Open the CIPO recordAbstract From the Canadian patent
A stabilizer for a mounting structure for a parabolic antenna of the type being mounted on a base and having an actuator to adjust antenna position has arms adapted to extend and contract to permit adjustment of the length of the stabilizer to correspond with adjustment of the position of the antenna. A brake is provided for locking the arms of the stabilizer in position relative to each other. The brake is operated by an electromagnet and is engaged and disengaged by a signal from the motor used to actuate the actuator. The stabilizer is particularly useful for providing additional support to an antenna to minimize damage due to wind and to maintain the antenna in a selected position.

Why it's free to use
- Filed June 10, 1992. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended June 10, 2012.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by June 10, 2014.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
