Tune your boom instead! The TH-7 is perfect for this.

Hello gang,
Has anyone thought of adding a set of 20 meter traps to the driven element
of a th7 to add 40 meters?
If so which traps, th5 or th6?
I have been thinking of this and putting the traps on the first driven
element then experimenting with the length.
This would give me a rotatable dipole on 40.
My first idea was to put a 40 meter two element Yagi on the th7 boom and
adding additional struts.
Any thoughts?
Glenn, VE6ND
