What are you building? Just experimenting?

I doubt there's a turn-key solution especially for 6m. There are some
companies that sell four-square boxes for the low bands, but they're
pretty pricey, and you're not going to get one for 6m.

I think the only plug and play phased array turner for 6m you're going
to find is an antenna rotator to turn your yagi :-)

Transmitting array steering is a bit more difficult than receiving
array steering. You can make RX array elements lossy enough to avoid
trouble with mutual coupling and you can get closer to doing arbitrary
phase combinations of elements, because you can do it with active
components. With a transmitting array in amateur use, you need to use
passive tuned networks, transmission lines, etc and it's harder to get
"weird" (non-90 or 180 degree phasing).

You might be able to put together an RX phaser... I don't know if the
MFJ 1025/1026 phase boxes go up to 6m but they might work for you for
RX.

Let us know what you're making. I'm curious!
