I drive the state quite regularly and I 'm wondering if I could receive the ASP on AWIN better if I made an antenna adjustment. I am currently using the Radio Shack 800 mhz duckie and don't really get great reception. Does anyone have an opinion on what type of improvement I can expect if I went this route (http://www.scannermaster.com/Antenex_B8065_Antenna_p/20-540972.htm) ?

Thanks for your time and input.
