Material:

Hot-dip galvanized steel.

Weather protection: Fiberglass.

Mounting:

On top of a suitable flange.

Grounding:

Via mounting parts.

Ice protection:

Even under icy conditions the antenna is still functional due

to the fiberglass covers for the feeding points.

Note:

Antenna may be mounted on top of Type 16911184 for higher

gain.

For climbing in the antenna special climbing rungs and attach-

ment points for climbing safety are provided.

Reflector grid and dipole parts must not be used for climbing!
