Duoband Yagi 6m/4m - 2ele. /3ele.
DH5MK6-4-5ele
Experimental design with two 50ohm Yagis on one boom. The 4m part is fed via "open sleeve".
The calculated values (EZNEV 7.0) look very good. The antenna only needs a 50Ohm choke.
The pictures are from the prototyp. Now the 4m director moved 20cm out.
