![TriBand VHF antenna for 2, 4 and 6 meter [homemade]](https://i.ytimg.com/vi/rvSkMXJQCdU/mqdefault.jpg "TriBand VHF antenna for 2, 4 and 6 meter [homemade]
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.
