MW antenna Bremen - top of the mast and top load

Fixing of the flat cage to the top of the mast.
Guys with egg insulators.
The grounded square mast (45 m high) is guyed three times every 120° at the top and approx. in the middle of the mast. The guy ropes are intersected by egg insulators. The design of the head of the mast allows to fix two ropes as top load and a flat cage additionally, all three every 120°.

The insulator of the top load
The two ropes of the top load are intersected by a rod insulator at the height of approx. 12 m.
|
|
These three photos show the top load, which is used for tuning the antenna impedance to 50 ohms.
The height of the insulator above ground and hence the length of the top load can be adjusted.
