Antenna kits

Antenna kits
nuxcom antenna kits contain nearly all parts needed to self construct yagi antennas in DK7ZB design. The kits do not contain mast connection clamps or boom supports. They can be purchased seperately as accessory if needed. More information on which parts are included can be found in each product details or on our antenna kit infosite.

28 Ohm, 12.5 Ohm or 50 Ohm? What does that mean?

In advance, all antennas can be connected to your 50 ohm coax cable. Low impedance antennas (28 or 12.5 ohm) are matched with a choke to 50 ohms. The needed cables for the choke are included in the kits.
  • 28 Ohm design antennas have the best gain / bandwith relation and may be used for all purposes.
  • 50 Ohm design antennas normally have less gain but more bandwith (there are exeptions - look for the diagrams!)
  • 12,5 Ohm design antennas have very low bandwith but relative high gain. These antennas can not be used together with other antennas on a mast and need a clear surrounding! Otherwise they will be detuned fast.
More detailled information on the antennas (gain, F/B, diagrams, beamwidt and bandwidth) are linked on each product details page as PDF file or can be downloaded in our download area on our website.
