{"replyTo":"","text":"Since we are all supposed to be transmitting at 4 Watts it turns out range is less about the radio and more about the size of your antenna, number of antennas,, quality of your antenna, the quality of your mount and installation and the location of your mount.\nAlso while on the subject of antennas, the supertruckers that point theirs antennas at a 45 degree angle into the wind are not gaining any effective range, CB radio antennas are omnidirectional which means they send out their waves in concentric circles around the mast, typically you can angle your antenna into the wind by a few degrees so that it stands up straight when being hit with an oncoming head wind, but anything more than that is shooting your signal up into the air behind you or down into the ground.\n4 to 8 miles depending on terrain and atmospheric conditions are possible with any standard Cobra 29, but if you have an older truck with aging antenna mounts you may want to rewire everything... also, factor in the length of your coax cable, Google is your friend.","replyToPid":0} |
