I am looking for a handheld DF unit capable of reasonable directivity on
40M.  I have excessive (+10 dB/S9)  power line noise centered near 7 MHz but
the noise is not very detectable at VHF/UHF.  I realize the gain will be low
for a handheld unit, but is there a device I can use to establish good
directivity at 7 MHz within a reasonable size for walking or mobile mounted?
