I know I could go to my EZNEC and find this out for myself,
but I figure someone here has already done this and a quick
answer is all I need..

In "normal" Yagi antennae, the elements are parallel
and at 90 degrees to the mounting boom.

In some TV antennae, the elements are at an angle to the
mounting boom, slanted in the direction of the station being
received. Otherwise, they look pretty much like a Yagi.

My question is, what effect does "slanting" the elements
forward have on the impedance, and the pattern ?

Thanks in advance for the meaningful answers..

Hi Andy

The TV antennas with the V shaped elements arent Yagi antennas. Log
periodic V antennas are fed from their "front end" to produce a minimum
toward the rear.
A TV Yagi antenna is good for any one channel. A LPV antenna is good
for all the channels but not as good for the one channel the yagi tunes to.
The LPV elements are slanted to an angle where their radiation pattern
adds in the Forward direction when they are a 3/2 WL dipole.
