I've not had good results hunting the null in an antenna pattern - at
least not on VHF. It is not always predictably straight off the back
of the antenna (and can vary with frequency.) But also it is very
susceptable to being confused by weak reflections.
In general, a null can be much sharper than a peak, but it only takes
a little reflection to shift it. It is a good idea to know what the
pattern looks like off the back of your beam, as, on occasion, it may
be usable. Just another trick to have up your sleeve.
The antenna for the LPER is not designed for a sharp peak, but rather
for a clean pattern in DF mode. For weak signal work, a larger yagi
or quad comes in handy.
