It is ideally suited for extreme climatic and operational conditions, where these antennas guarantee max. strength, stiffness and reliability. It requires very low maintenance. The antenna mainly operates as a vertically polarized radiator with an omnidirectional pattern. It can be used as both transmitting and receiving antenna. Receiving antennas may be equipped with wideband toroidal core matching transformers types EAU 60/240 resp. EAU 60/240/II as per data sheet.

Mechanical Specification Installation Proposal Design This very robust antenna is the result of decades long experience with glassfibre reinforced synthetic resins. The electrolytic copper radiators are embedded into the resin laminate. The antennas consist of two sections. The lower section with its base insulator has a length of approx. 3 m. This self-supporting lower “mast” section is connected with the upper section by means of a junction assembly. Upper sections are available with lengths of 1, 2 and 3 meters. The antenna is absolutely non-magnetic. Required Space Only a minimum of space...

Application When the antenna transformer is used, short rod or wire antennas (3 to 15 m) can be connected to a coaxial cable. The antenna transformer considerably improves the efficiency of the receiving antenna, particularly in the lower frequency range, and protects the receiver from static charges. Because of the high RF power limit of 100 W, the antenna transformer can also be used for receiving antennas which have been set up close to transmitting antennas.

With supporting pipes and tilting mechanisms (our tilting flange K 8 is shown on picture 7), these antennas can be used in a wide range of installation setups. An illustration of available ground networks is shown in picture 9. Mounting Proposal Picture 5 RF power is being injected through the base of the antenna as a standard (internal feeding as per picture 4). It is, however, also possible to supply the antennas as model STA … PM equipped for external feeding according to picture 8.
