In order to service different areas at small to large distances the Rotatable LP Antenna AHL 0421 is recommended.
The vertical radiation pattern of this directional antenna is dependent on frequency and height above ground.
It provides an excellent solution for applications where large distances require higher frequencies and medium distances lower frequencies and where changes in azimuth are necessary.
The antennas are designed and fabricated with quality assurance uppermost. The basis for mechanical loading calculations is DIN 4131 and higher load factors can be accommodated on request. The choice of materials is based on long term experience gained in the field of corrosion and statics. For example, HF conducting parts such as dipoles and feed lines are fabricated from sea-water resistant aluminium or aluminium alloys, the smallest fan antenna also makes use of fine stranded bronze rope. Fixtures and standard parts are made from stainless steel. Guy ropes are fabricated either from stainless steel or Parafil. All insulators are made from glazed low-loss ceramic. The masts are constructed from hot-dip galvanized steel. 皇冠金花下载
