WiMo acquires EAntenna
Herxheim, August 24., 2018
Germany’s largest provider of amateur radio products announces the acquisition of the spanish antenna manufacturer EAntenna.
EAntenna
WiMo Antennen und Elektronik GmbH (Herxheim) will take over sales, service, manufacturing and the trademark of the Spanish manufacturer of short-wave antennas, ‘EAntenna’ from Brenes (Spain). EAntenna has been manufacturing a broad range of HF and VHF / UHF antennas, masts and accessories since 2010. The antennas are used internationally by radio amateurs and commercial radio services for worldwide voice and data communications, and are offered by 20 distributors worldwide.
Volkmar Junge, Managing Director of WiMo: “WiMo has been the largest distributor of EAntenna for a very long time now. Our sales and service teams know the entire EAntenna product portfolio. As we already have our own production lines for a wide range of antennas, we see great leverage in the consolidation of the Spanish production into our manufacturing in Herxheim. This will enable us to provide our customers with the premium support they are used to getting from WiMo’s own product range.”
The former owner of EAntenna, Rodrigo Herrera, EA7JX, will move to Herxheim with his family. Both he and his wife Angeles, who also has extensive knowledge of the EAntenna product portfolio, will continue to work for WiMo after the takeover. Rodrigo Herrera: “We now have the chance to develop the EAntenna product portfolio and take it to a totally new level with a very strong partner. We are very happy and excited to be able to work for WiMo in Germany.”
Volkmar Junge: “The fact that key personnel of EAntenna will continue to work for us is going to ensure that there will be a smooth transition of the production and customer orders can continue to be delivered on-time. At this point, we have enough EAntenna products on stock and lead-times should be below three weeks. In addition we can now offer Spanish, Portuguese and Italian support for our entire product portfolio and we expect to improve our presence in these countries.”
Production will move from Spain to Herxheim in September 2018.
WiMo Antennen und Elektronik GmbH is Germany’s largest provider of amateur radio equipment, antennas and accessories. With more than 40 employees, the company location in Herxheim (Rhineland-Palatinate, district Südliche Weinstraße) is home to a production facility for antennas, cables and accessories. In addition, WiMo offers amateur radio gear from most well-known manufacturers plus a wide range of accessories with more than 4500 products.
EAntenna is an owner-managed company in Brenes (Andalucia, Spain). With 6 employees, Rodrigo Herrara has been building up a renowned brand for antennas for almost 10 years.
