i have a uniden bc75xlt and the stock antenna is absolutly terrible its not always reliable in clarity and cuts words here and there. i use it for a raceiever for dirt racing and cant always hear the caller. i was looking to see if anyone had suggestions for a really good antenna using the BNC connector im no more than say 75 yards from the transmitter. i hear the stock antennas are useless so i hope for a good antenna tuned specifically to that 450-470 or 430-470 dont really matter cause i mainly use the 454 band.
