"QRM Eliminator" for poor man's antenna phaser? (lemmy.basedcount.com)

Hi all. Does anyone know whether I can use the $50 QRM Eliminator X Phase as a cut-rate antenna phaser? I thought maybe I could just use two of the same antennas, one on each antenna input, and phase between them to beam steer rather than to reduce interference.

I can't comment on that one but I have the MFJ-1026 and it works exceptionally well but there are caveats - it can only eliminate what both antennas hear and (as far as I recall) are similarly polarized.

In my case it is effective in eliminating noise from my daughter's older TV and some other suburban interferences.

It takes a little time to get used to using but, once you are, tweeking for the best signal becomes natural.

I can't comment on steering reception because I've never really used it for that purpose. I suspect it would work depending on the geometry/positioning of your antennas. A Yagi or beam antenna would be more effective.
