Hi Scott,
It says uni-directional in the website text both for the 708 and 709 as
well as the picture of the base. This informed my buying decision.
My 'informal test' consisted of inverting the mic through 180 degrees
while monitoring the speech quality (with SP off). Off the side. levels
are similar to the front but off the back, room reflections apppear to
predominate.
It sounds very different off the back to the front but the masking
effect of the internal capsule mount and gooseneck end together with
need for lip contact and 100 MIC gain needed to get ALC to flash may be
contributing to this impression.
I will contact the UK importer about the mic.

Good morning,
We've made an error in the way the microphone was designated on our
website and literature - the 708 and 709 series microphones are
omni-directionals. Everywhere I've looked, it says "uni-directional"
except on the base of the production microphone itself, which reads
(correctly) "omni-directional".
The picture that reads uni-directional on the base of the microphone on
our website is even wrong - that picture was taken (by me...) of an
earlier prototype version of the 708 with a different element installed.
We did not use a uni-directional in the 708.
I'm going to fix the website later this morning. I'm not sure where the
blame lies, but since I proofread both the website copy and the
information sheet enclosed in the product box and took the picture on
the website I suppose I get my share :-)

Together with my excellent O2 I purchased an excellent Ten Tec 708A
unidirectional microphone which an informal test shows as indeed being a
cardioid or 'uni-directional' microphone. The Ten Tec website includes a
graphic at http://images.tentec.com/radio/products/708/708Base.png which
shows 'UNI-DIRECTIONAL' on the base yet *my* 708A contradicts this,
having 'OMNI-DIRECTIONAL' printed on it.
I am awaiting Ten Tec's verdict on this anomaly but I hope this proves
to be incredibly rare, like a postage stamp printed upside down and will
eventually be worth millions. Once a provisional valuation has been
established I will eventually consider bids which recognise the extreme
rarity of this article (dollars, pounds or euros accepted provided there
are enough 0s in the figure).

Or I might just use it...
