We show below a table which should allow you to compare rotators before purchase. We've not included rotators only suitable for small HF tribanders or VHF antennas. These are sometimes described by other retailers as "Heavy Duty Rotators", whatever that means (?).

More details of the rotators listed below are available on the Rotators main page.

For controller features.  See Relevant page.

The above are manufacturers claims. Virtually any rotator will turn any antenna in still conditions with appropriate gearing. It will just take longer for the smaller rotators to overcome the antenna inertia and get up to speed. When braking is considered, a totally different series of considerations comes into play, including the weight, the wind area, and the wind balance of the antenna(s). Also - check out if your rotator ramps down slowly to a stop, or if it jerks your antenna to a halt. All our PST rotators have selectable ramp-down speeds - kind to your antenna and to your tower. In our experience, and from customer feedback, we feel that the braking specification for gear train braked rotators should be treated with caution. Customer feedback, (insurance claims particularly!), indicates that their braking effort specification should be derated by at least 50%.

Do please discuss rotator purchase with us before you buy. The bells and whistles aren't what holds the antenna in place in a storm, and as we aren't general amateur equipment suppliers we don't treat a rotator as just another box to be shifted. Our advice costs absolutely nothing, and people like the RadioCommunications Agency, Universities and Government Departments buy from us, as we are ANTENNA SYSTEM SPECIALISTS and can recommend the right solution.
