HI .. hey, back in the days of yore, there was such a bearing gadget built 
commercially ... trying to remember the brand ... Hy-Gain, perhaps?  Anyway, 
I had one might be in the jungle part of my back yard .. HIHI .. and I 
had it on top of a W-67 w/ 20' mast ... The antenna wires raised havoc when 
raising the tower, and I eventually gave it up as a nice experiment.  I 
cannot say my signals were improved, cannot remember exactly, but I was not 
impressed.  This was back in the 70s, and I was in an area with a great 
ground .. old riverbed -- and my 65' high vees worked pretty swell, and on 
40m I had steerable verticles that beat the vee.  But, point is, there 
is/was such a device.
