What Is a Tower Hazer?
A plain-English guide to hazers, antenna lowering systems, and how they keep you off the tower.
The short answer
A tower hazer, usually just called a "hazer," is a carriage that wraps around your tower and carries your antenna. A haul cable runs from the hazer up to the top of the tower and down to a winch at ground level, so you can raise and lower your antenna without climbing. 413 Built builds aluminum hazers for Rohn 20/25 and Rohn 45 towers.
How a hazer works
A hazer clamps onto the legs of your tower and holds your antenna (or your rotator and mast assembly). A haul cable runs from the hazer up to the top of the tower and back down to a winch at ground level.
When you turn the winch, the cable pulls the hazer and your antenna up the tower. Release the winch and the hazer travels back down. You control the entire raise and lower cycle from the ground, no climbing required after the initial install.
Why operators use a hazer
- Ground-level access to your antenna for tuning, service, and adjustments
- No routine climbing, which is the biggest safety win over a fixed mount
- Bolt-on installation with no welding or permanent tower modifications
- Works for both HAM and CB operators on Rohn towers
Hazers for Rohn towers
Not every tower is the same, and a hazer has to match the tower it rides on. 413 Built makes two main hazers:
- Rohn 20/25 hazer: built for Rohn 20 and 25 tower sections, available in beam and ground plane variants.
- Rohn 45 hazer: scaled up for the heavier, wider Rohn 45 tower and larger antenna loads.
If you run a different tower or a modified section, reach out before ordering and we will talk through fitment.
Beam vs ground plane hazers
The Rohn 20/25 hazer comes in two configurations. A beam hazer is set up to carry a beam (directional) antenna, while a ground plane hazer is configured for ground plane antennas. When you order, tell us which antenna style you run so you get the right variant.
Winch options: hand crank vs electric
A winch is what raises and lowers the hazer. 413 Built hazers work with standard hand crank winches, so you can run one with a manual winch if that is what you have.
For fast, effortless operation, the 413 Built Winch Box pairs a 2500 lb rated ATV winch with a weatherproof steel housing and clean wiring. It is a standalone unit that works with any 413 Built hazer or on its own.
What installation involves
A 413 Built hazer is a bolt-on system, no welding and no permanent modifications to your tower. The basic process:
- Mount the hazer carriage to your tower legs.
- Attach your antenna (and rotator / thrust bearing as needed).
- Route the haul cable from the top of the tower down to your winch.
- Connect the winch and raise and lower from the ground.
The initial install does require climbing, so follow safe climbing practices or work with someone who does. After that, day-to-day operation happens from the ground.
Is a hazer right for you?
If you run a Rohn 20/25 or Rohn 45 tower and you want ground-level access to your antenna, a hazer is a straightforward answer. It is built for CB and HAM operators who would rather work on their gear from the ground than climb every time something needs attention.
