I have a Crobra 29 NW LTD Classic CB radio with a 39 doller Radio Shack antenna on my merrier but when I key up the needle only goes up to to the "9" in the green NOT all the way up to the +30dB like I thought it should. Could this be an issue with the way I hooked it up ? A antenna issue ? What can I do to get the max power out of this thing ? I know it works because I talked to someone who was right behind me but I know that's not far. Then the next day i tried it and nobody answered me while i was on the (capital beltway) Any help with this would be appreciated.
