Or... another possibility, though single-frequency, is a Moxon. There
was an article in QST around 2001 for a 136-mhz receiver cum Moxon
antenna unit specifically for RFI hunting. The beauty of the Moxon is
that it has a deep narrow null in the reverse direction, so you can turn
the antenna around and pinpoint the source quite precisely. I use a
homebrew one with a cheap Icom handi that has AM reception on the
aircraft band. Works pretty well, even if it *is* ugly.

If you're looking for log periodic yagi
that covers amateur frequencies I just happened to pick up a QST, June
2013, pg. 56 "Short Takes" column by Steve Ford, WB8IMY. There, he
reviewed
a hand held VHF/UHF Log Periodic Yagi from Elk Antennas, model 2M/440L5.
I have two of them, my intention being to mount them broadside,
replacing a TV antenna I don't use for 2 and 440. It's on the to-do
list.
Thing is, an LPDA pattern can be quite wide, as is a short yagi's. You
need a long yagi to pinpoint soucces.
