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! Dan N3OX |

Hmm...
You could build a 6 meter array of verticals, a four square or a rectangle array or something. It may be a little touchy to adjust for proper phasing, but it could be done if you've got your heart set on phased verticals. You're not going to find a commercial phasing box for 6m though. The only commercial transmit phasing unit I know of is this: http://www.dxengineering.com/Parts.a... o=DXE-TFS-1P And it's for 160, 80, 40... If ice survival is your only concern, maybe you should just add heaters to your yagi :-) Good luck... Dan N3OX |
