I am trying to decide which antenne is better for a scanner. I have it down to the Comtelco All-Band Low-Profile Mobile Antenna located at http://www.scannermaster.com/Comtelco_All_Band_Low_Prof_Antenna_p/07-540719.htm . Or the Antenex ABSCANC located at http://www.theantennafarm.com/catalog/index.php?main_page=product_info&products_id=1048 . Which one is better, and does anyone know how tall the comtelco one is, i cant find it. thank you if anyone can answer it.
