This 1:1 balun is suitable for wire dipoles and helps reduce feed line radiation and radiation pattern distortion.
Specifications
| Frequency range | : | 1,7-40 MHz |
| Impedance | : | 50 Ohm |
| Max. power | : | 1,2 kW PEP |
| Max. width | : | ca. 7 cm |
| Height | : | ca. 11,5 cm |
CAUTION
DO NOT use this balun with any type of antenna tuner or match box when the VSWR (before matching) is greater than 3:1. If the VSWR is below 3:1, a match box can be used as long as the power levels are kept below the limits shown in the Specifications. When these power and VSWR limits are exceeded, the extremely high standing wave voltage present at the feedpoint causes the breakdown voltage of the balun to be exceeded.
WARNING DIAMOND!
While using the new digital modes FT8 / FT4 / WSPR, there is an excessive load for the antenna and other equipment due to continuous carrier broadcast. Then reduce the output power for all Diamond antennas to max. 1/5 of the specified SSB(PEP) max. power. .
