Hi 7P8BA

Go download Gamma software http://www.ve3sqb.com/gamma2002.exe

and you can see this page http://www.ve3sqb.com/

and you need MMANA-GAL software for deferent antenna design http://mmhamsoft.amateur-radio.ca/files/programs/Galana_v0.3.zip

see this page http://mmhamsoft.amateur-radio.ca/mmana/index.htm

I do calculate for you 2EL 10.1 MHz see the picture

I tried to find how Tennadyne makes a T3 beam that appears to be a 3 element beam for 30m on the same size boom. Couldn't find a manual on their website or pictures of the T3 beam.

I think a reflector is the best way for 2 element beams.

Not in my case.
In my back only Antarctica with just a few stations there,so I don't need
to press them,no QRM from South at all.Using driving el and director I can get
more gain,so stations can here me better.

In your case you need Reflector and Drive element or you can used only single
Element as rotate dipole.

Driven el + director got a little bit more gain than reflector + driven el.
In Europe or Middle East when you guys rotate your antennas you need to
press down QRM from other stations from back.
The point is - for me it's not necessary,because there is nobody in my back,so I can go for better gain with driven el + director.
I did recalculate the sizes,and compare,your info help me a lot to build it.
Thanks one's more.

Fine but we need some photos for that.

good luck and 73.
