The DK7ZBDualbandMoxonBeam for 10 m and 6 m
One feedpoint with 50 Ohm for both bands! This Minibeam has for 28 MHz 2/3 of the dimensions of a fullsizebeam and is an opensleevefed 2El.Yagi for 50 MHz Gain 10 m = 4,0 dBd F/B = 30 dB Gain 6 m = 4,3 dBd F/B = 11 dB

The DualbandBeam built by Aleks, S54S
He has bent the corners, very good solution if you can handle this method! 
The feeding system of the Moxon by Aleks, S54S
Aleks has just used the dimensions given on this page, no further adjustments were needed. Mni tnx for the informations, Aleks!

For the connections of the bent ends I use Cufittings. The lengths in the upper table mean the distance from the center of the tubes to the other end. Pay attention that the middle parts 2, 4, 7, 9 must be longer and can be shifted in the 16mmtubes for tuning!
