Product Information
  • Overview
  • Description
Dimensions 210x17x11cm, Weight 14kg  

EAntenna OWA antennas for HF, represent the highest development of HF antennas for its great features.

This performance is characterized in that:

  • You can listen to very low signals without QRM and QRN noise alters the audio clarity.
  • Direct feeding is 50 ohms, using supplied Balun.   
  • The bandwidth of the OWA is the best technology development for the entire width of the band, and have low SWR / SWR.
  • The radiation pattern is similar to the LFA, but has more gain than these.
  • Its ratio of F / B is medium to high, offsetting the high gain front.

This is explained because in EAntenna:

  • Millimeter by millimeter, manufacture and build CNC machines and / or prepared to hundredths of a millimeter measurements for an accurate measurement.
  • It takes care of every piece of aluminum, by filing them smooth exterior and interior. All this by hand, skilled and prepared for a final product of extreme quality.
  • All hardware we use is in stainless steel AISI 304
  • The T5 aluminum used is 6061/6063 and 6082 T6, the best alloys for manufacturing antennas and resistant to the weather elements.
  • Always LFA EAntenna antennas are insulated from the boom, with German clamps PP (Polypropylene, -30 ° C / +60 ° C).
Specifications 28OWA5
  • Square 45x2mm complete boom.
  • Items divided into 2 sections; central 20mm diameter and 15mm tips.
  • Mast plate of 150x100mm with 6mm thick with square U-bolts M8 boom to the plate and U-bolts of M8 to the plate to the mast.

Characteristics of the 28OWA5

  • To take advantage of both low solar cycle in full swing, you can achieve incredible results in this band. With a bandwidth will get amazing high gain wide band width
  • With a rotor G450 / CD-45 have enough to rotate and resist the wind, because wind resistance offered by the elements is minimal.
  • Simple and quick, because the boom joints are easy to assemble. And the elements are attached by screws DIN 912 M3 Interns and Endless Clamp (Hose Clamp) for Driven to a quick and durable fastening.
  • Antenna very solid construction, and with an acceptable weight.
