It does make a difference.  All airband communications use vertically-polarized antennas.  The cross-polarization difference (loss) can be from a few dB up to 20dB, depending on how the received wave rotates through free space and when it encounters obstacles.  

The rule of thumb with antennas is to always match polarizations at each end.  One exception to this is satellite communications where circular polarization is often used.

Nice classic scanner, nice condition too. Interesting to see how the Realistic/Radioshack handheld lineage has retained the same basic keypad layout even to this day, it works great.

I am using the HP antenna. It IS my TV antenna, I know  embarassed  My antenna mast is too short to add my groundplane antenna. I am considering adding a second mast at home, at a higher spot. I hope that on the following days weather and my wallet will allow me to do that.

SBFI, if you do take it down, drill some extra holes in the mast, and mount the antenna for vertical instead of horizontal polarization. Your feed sounds great as it, but I bet some of the weaker transmissions I heard will come booming in.
Good job on the set up

Thanks for the advices guys. I am convinced that I have to change my antenna. I won't remove the TV antenna from where it is - it will be much easier (and better, because the it will be at least 8 ft taller) to add a second mast.

Cheers all,
