Just curious if anyone has shortened their radio antenna and if so was there any negative impact (i.e. reception).
Not sure about your intercom or your CB unit but your transmitting antenna needs to be a specific length. A standard calcuation for a full wave antenna would be 486/freq in Mhz and divide that by 4 to get to a 1/4 wave size. using 27.2Mhz as a midpoint for the cb band would result in an antenna approx 4.5 feet in length. CB antenna mfgs quite often use a coil or wind the antenna on a fibre core to keep the length down. So dont cut your CB antenna unless you have a reliable SWR meter or ant analyzer and know what your are doing or you could wipe out the final amplifier in your CB radio. Just my .02zimbazi said:Does it make any difference on the CB antenna....?
My CB antenna is much longer than the radio antenna.
Is anybody else having problems with the J&M CB unit?
My bike is 2006 and the CB has never transmitted correctly......?
