Amateur Radio

Yagi 6m-2m-70cm

Omni/dipolantenner

For home construction


Ambition: Our goal is to deliver the best possible end product to our customers. With the long experience, knowledge and measuring resource we test and evaluate antennas characteristics compared with data calculations. This applies both to the efficiency and the radiation of the antenna. Materials and detailed features of long-term test on our MEASURING SITE which lies close to the Baltic Sea with strong winds and salty air. For example, modulated Yagiantennas with the help of computer programs, are test built and radiation meausured at our measuring field to verify the calculated data . Radiation and front to back measurement is the most important parameters to verify. V.S.W.R which is the parameter easiest to measure is the least important, it's always possible to transform the radiating resistance to tha cable and transmitter. To our calculations, and controls we do "real world" tests of the performance on amateur radio station SK7MW that now has been Nr. 1 in the Nordic Activity Contest for 10 years in a row on both VHF and UHF. This demonstrates our high quality both in mechanics and antenna optimization. Sample antennas are mounted near to the Baltic Sea coast and are exposed to both strong salt air and strong winds - with no problem in 10 years!	It began in 1967! SM7DTT Sven Jacobson in an early antenna for 144MHz.
Recommendation: For those who want to buy our plastic components for 5 mm (VHF & UHF) and 3mm (1,3 & 2,3 GHz) rods and the other parts we can recommend YU7EF and DK7ZB's websites with many fine designs for both VHF and UHF. These calculations are made for 'free space' and this fits our plastic element holder perfect. The antenna element has no contact to the boom and floats freely. In this way you will obtain the best efficiency of the yagi antenna. Observe that if the elements are not 5 or 3mm some calculation for the rod leinghts must be done.
