Comet 2M/220/70cm Mobile Antenna (Black), 2.15/3.6/6 Gain, 36" Length, PL-259 Connector Comet mobile VHF/UHF tri-band vertical antennas offer three bands of performance in a choice of lengths. These well-designed black-anodized Comet antennas can handle less-than-perfect weather and top highway speeds. Their fold-over design has a hinge that rotates 360 degrees inside of the socket, so it can fold in any direction when you need to do so. And, when you don't--say, when you're going down the road--some styles feature a threaded collar around the hinge. You won't have to worry any longer about the antenna spring expanding causing your antennas to "lie down on the job"!
