  • The bandwidth is broad to cover all part of Amateur Radio.
  • The radiation pattern is banstante wide, so even some in fixed position will get a wide range of correspondents from different latitudes.
  • These antennas are prepared both for FM, SSB and CW, but positioning it in Vertical and horizontal respectively.

  • 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 EAxxZB of EAntenna antennas are insulated from the boom, fitted with "Made in Spain" PA (polyimide, -40 ° C / +70 ° C).
  • We include detailed manual mounting and up videos on our site, which are indicative of assembly of some models.
  • Do not be satisfied until our client has its antenna mounted and work with it. So, whenever you need or have any questions or comments, contact our customer service department, and direct with Rodrigo, EA7JX ( ea7jx@eantenna.es ), which we will attend as quickly.
