I made a TriBand antenna for 2 meter [145MHz], 4 meter [70MHz] and 6 meter [50MHz].
The design is made by DK7ZB.
There are 7 elements, 2 for 6 meter, 2 for 4 meter and 3 for 2 meter.
There is only one [1] element for a feed and so you have only one coaxcable.
This is done by using the 'Open-sleeve methode' and one balun.
The theoretical gain is about 4 to 6 dBd so quit nice.

![The Buran Russian spacecraft
The Buran spacecraft (Snowstorm or Blizzard), GRAU index 11F35 K1, was the only completed and operational space shuttle vehicle from the Soviet Buran program. Clearly influenced by the earlier American Space Shuttle design, the Buran completed one unmanned spaceflight in 1988 before the cancellation of the Soviet shuttle program in 1993.

![Liftoff - Juno spacecraft on its way to Jupiter
At T minus 4 minutes liftoff is on hold, this is standard procedure. After checking all the systems [some issues with the helium, boats nearby] countdown goes on.
Voice-over is Atlas launch controle
Key things to know about Juno
Spacecraft was launched on Aug. 5 at 12:25 p.m. EDT [US] - 16.25 GMT
Five-year cruise to Jupiter, arriving July 2016
Spacecraft will orbit Jupiter for about one year (33 orbits)
Mission ends with de-orbit into Jupiter
Juno will improve our understanding of our solar systems beginnings by revealing the origin and evolution of Jupiter.
Specifically, Juno will...
Determine how much water is in Jupiters atmosphere, which helps determine which planet formation theory is correct (or if new theories are needed)
Look deep into Jupiters atmosphere to measure composition, temperature, cloud motions and other properties
Map Jupiters magnetic and gravity fields, revealing the planets deep structure
Explore and study Jupiters magnetosphere near the planets poles, especially the auroras Jupiters northern and southern lights providing new insights about how the planets enormous magnetic force field affects its atmosphere.
