I have a uniden BCT8 scanner with a basic all band antenna and want to upgrade to a low profile for the 800 mhz range, mainly 866 mhz. I have found two companies that offer similar products for practically the same price and was wondering if anyone could suggest one or the other. The first is the Comtelco A4681W-806. The others are Antenex brand. The first being the ETRAB8213 (the phantom elite) or the TRAB8213. If anyone has advice please let me know. Thanks.
