75 to 50 ohm mismatch at the scanner is a 1.5:1 SWR, not much to worry
about.  And some of the 75 ohm aluminum shiellded cable is VERY LOW loss
for the price.  As for the TV antenna, it's probably designed to mount
horizontally, with a mast up the center.  Trying to mount it vertically 
may be a problem both mechanically and electrically, as a mast in line
with the elements will probably affect it a lot.  Don't get me wrong, I've
used "other" antennas for lots of stuff like scanners and even transmitting.
I'm now using an old Radio Shack VHF high band only base monitor antenna
for a 2 meter transmitter.  Believe it or not, I had to CUT the length 
down to make it tune.  I get EXCELLENT results.  (This is the old antenna
that was discontinued in 1977 that has a base loaded coil.  They sold a 
base version and a mobile version that were nearly identical.  There was a 
taxi company near me that used the mobile version for their taxis, seems
$16.95 was a lot cheaper than the Motorola antenna.)  

On scanners, almost anything will work.  Just get the antenna OUTSIDE and
get it as HIGH in the air as you can.
