ELNA-Rod-Antennas

Product catalog summary
Overview: The document outlines specifications and installation instructions for the STA 50-70 series rod antennas, designed for marine environments. These antennas are constructed from glassfibre reinforced polyester resin.
Specifications:
  • Construction: Two-section, self-supporting rod antennas with brass screw joints and molded polyester resin base insulators.
  • Material: Glassfibre reinforced polyester resin for rods, brass for coupling.
  • RF Connection: N-system 50 Ohms for receiving, copper screw terminal for transmitting.
  • Color: Light grey, similar to RAL 7035.
  • Length and Weight: Models vary in length (5m, 6m, 7m) and weight (4.4 kg to 6.2 kg).
  • Wind Load: Maximum 200 km/h.
  • Environmental Resistance: Resistant to seawater, exhaust gases, chemicals, icing, microbes, and white ants.
Features:
  • Vertical polarization with solid glassfibre rods.
  • Sectional assembly for rigidity and low weight.
  • Simple mounting with approved techniques.
  • Optional features: tilting (K), reinforcement (TR), transformers (EAU).
Mounting Instructions:
  • Assemble upper and lower sections before installation.
  • Screw and lock brass fittings with fork wrenches.
  • Attach base insulator to counterflange with stainless steel screws, torque 40 Nm.
  • Install at a slight angle (5 degrees standard, 20 degrees TR version) to reduce motion.
  • Various mounting supports available for different angles and structures.
Models and Variants:
  • Receiving Antennas: STA 50 E, STA 60 E, STA 70 E, with options for transformers, tilt, and reinforcement.
  • Transmitting Antennas: STA 50 SE, STA 60 SE, STA 70 SE, with similar options.
Additional Information: ELNA may change specifications without notice. Includes details on optional accessories and recommended installation methods.
Specifications: The document also covers STA 50-70 SE and STA 80 SSB/E models, designed for low power radio stations. They operate within 1.5 to 30 MHz for transmission and 0.1 to 30 MHz for reception, handling up to 1000 Watt HF power. Available in lengths of 5, 6, and 7 meters, with custom lengths on request.
Maintenance and Service: Minimal maintenance required. Periodically check and clean lower area for pollution and salt deposits. Annually check fixing bolts and RF connections for tightness. Do not paint the plastic mast.
Optional Accessories: Include mounting supports, a mounting set with stainless steel fittings, and matching transformers to enhance installation and functionality.
Application: STA 80 SSB and STA 80 SSB/E models are self-supporting antennas for marine radio communication, covering 1.5 to 22 MHz. They are reliable, lightweight, and require minimal maintenance, ideal for vessels.

Empfangsantennen / Rece iving ROD Antennas STA 50 – 70 E Mounting Instructions Deflection at wind 6 (Beaufort) The antenna consists of two parts: the upper and the lower sections. The antenna must be assembled before installing. The brass fittings of both rods must be screwed together and shall be locked then by two fork wrenches, 30 mm and 22 mm size. The base insulator of the antenna shall be screwed to a prepared counterflange. The flat gasket belonging to the delivery scope shall be used with all installations, because it serves not only as a sealing, but it also compensates unevenness on...
