EAxxZB EAntenna series are antennas designed by the super-known, Martin Steyer, DK7ZB. 
Amateur drove the new antenna design, using the new software today, which were based on characters like YU7EF, G0KSC, to have their current designs. Martin, after many years basing on designs of their countrymen DL6WU DJ9BV and with continued many antenna designs that have occupied the first places in competitions winning seasons, and filling facilities people do not like their own antennas.Seeing that some of their antennas are not yet improved, we agreed to make some of their models.Antennas with high demand and aseguible price. Topics tomasmos always considered in EAntenna, that quality does not have to have a high price.

This performance EAxxZB are characterized:

  • Peak gain antennas and a F / B acceptable, taking into account the lengths of separation and boom length.
  • Antennas are multiband, single decline of direct coaxial 50 Ohms.
  • The bandwidth is broad to cover the entire Amateur Radio.
  • The banstante radiation lobe is wide, so even some of them in a 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 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, by 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 EAxxZB EAntenna antennas are insulated from the boom, with pieces "Made in Spain" of PA (Polyimide, -40 º C / +70 º C).
Specifications EA270ZB5
  • Boom sections square 25 × 1.5 mm.
  • 6mm elements. in diameter, including excited.
  • Originally this antenna because of its small boom, is to position it in front of the mast, and avoid interactions with mast and even to put on balconies or handle it with your hands on the Fox hunts.
  • The mast plate of 100x100mm with 6mm thick with square U-bolts M6 boom to the plate and U-bolts from M6 to the plate to 50mm maximum mast. in diameter.

Features of the EA270ZB5

  • Both for if your dedication is FM or SSB in some cases, this antenna provides good gain for a boom in such small dimensions.
