Hi Fabio,
Try the designs by Sommer and consider a double sized version of the
Tribander. TET HB35 C is similar, this design uses HB9CV principles, the
two elements are driven and a resonator is placed in front of the driven
array to gain resonance on what is normally 15 metres and another in
front to resonate on ten metre. Doubling this would give a 2 ele HB9CV
on 40 M, a two elem three quarter wave length radiator on 30M and a full
size 4 element array on twenty metres. This is what I am planning for my
new QTH.

Subject: [TowerTalk] 40 mts moxon and 20 mts yagi
Hello !
I wish to build a dual band antenna for the 40 and 20 mts bands. I have
a 33 ft 3" diam. boom and I am thinking of a two elements moxon
rectangle for 40 mts and a 3 or 4 elements yagi for 20 mts.
Any idea, suggestion (or even an already made project ?).
Best regards and 73,
Fabio, IT9GSF.
