[Antennas] anyone have experience with the HyGain DIS-71?

[FireBrick]

I really need to improve my 40/30 meter antenna.

Has anyone had experience with this antenna.
>From the Manual, it looks like a relay could be use to switch from 40 to 30.

Has anyone tried this?

I'd appreciate the info, thanks.
