i was wanting to know if i get a 4ft valor antenna instead of the 18 inch would it make much diffrence in the reception

If it's a CB 4' antenna you are wasting your time.
this is the 18 inch scanner antenna http://www.universal-radio.com/catalog/scanants/2246.html this is the 4 ft scanner antenna http://www.universal-radio.com/catalog/scanants/4421.html would the 4ft get better reception or not make no diffrence

I would guess that the longer one might receive better on the VHF low and high bands. On UHF and 800 MHz there probably wouldn't be much difference. This is just a guess on my part as I have not used either of these antennas.

Hey there TB, Ken is hookin' you up with the right stuff above. The 4'er will be substantially better for VHF and below down to around 27-30mhz (10 & 11 Meter Bands which include CB). On VHF the 4'er is the same length as a 5/8-3/4wave antenna for these frequencies (144-170mhz) or thereabouts. Then decreasing in efficiency as you decrease in frequency from VHF. At 27-30mhz, you're down to around what would be a 1/8 wavelength here. Pretty much any verticle antenna design which drops much below 1/4 wavelength and you lose all of the gain factor.
And this ( have a tuned antenna with gain) of course is only critical for transmitting. Receiving-only is a more passive energy function. The Valor you're looking at is claiming 30 mhz - 1.2 ghz. range. It looks like a typical helical wound 4 foot ant. except without any tuned circuit for a specific freq. range although it chances to look just like pretty much any brand of 4' helical wound mobile CB ant. such as a "4 foot Firestick".
Very decent antenna (the Valor) with a magnet base for $25. So if your scanner covers those top to bottom freqs. and you definately want to be able to scan this 30-1.2ghz range and have a good chance of receiving decent signals throughout, then this Valor is a good or great choice for the bucks.
good luck
