The M0CVO Antennas VaxTenna.
Five band loaded dipole for 10m, 15m, 20m, 40m and 80m (only loaded on 80m). SWR below 1.5 throughout the whole 10, 15 and 20m bands, <3 throughout the 40m band and <2.4 from 3.640 - 3.80MHz on the 80m band (SSB Portion). This is fitted with a M0CVO 1:1 BALUN at the feedpoint and can be fed with standard 50ohm coax. An inline ATU is recommended, especially in the 80m band to extend the tuning range.
Overall length is just 24m so will even fit in small gardens. It is best mounted as an inverted vee, as in the image above, but other options may be suitable in order to fit in the available space. An ATU may be required for some bands and is always advisable if used with an amplifier.
Bands: 10m / 15m / 20m / 40m / 80m/font>
Max Power: 400W CW, 550W SSB*
This power rating is for intermittent amateur (CW or SSB) use and not for AM broadcast or constant carrier data modes. For these modes a much higher rated BALUN is required.
