How about these:

or many from this list:

Ok, I'm mainly kidding since the majority of these analyzers are far too
expensive and often difficult to lift.
The point is that you do need a reasonably sensitive frequency analyzer
or at least a counter for site surveying, and that counter should not be
restricted to the ISM / UNII bands (mind the harmonics!). So, if you
can't afford the big guys, even a Zapchecker can come handy. After all,
it has a decent SMA connector you can plug in any antenna you want
(could be a tupperware or pringles just as well).
Ok, this may not be directly related to wireless pentesting as many see
it, but we consider a decent site survey to be an important prerequisite
of a proper wireless pentest (in fact, a prelude to it). Besides it is
very useful when performing forensics / incident response on WLANs.

The main problem with home brew antennas is verifying their parameters
(beamwidth, coverage zone shape, gain, VSWR etc) with sufficient
precision. Something like

comes handy, but then there is again that pesky price problem.
