These are new and excellent NMO antenna coils from the Midland 18-311A series antenna. The coil is rated at 300 Watts and has a frequency range of 136 to 174 MHz. Perfect for 2 meter ham and commercial or farm use. You get the NMO coil, washer and allen wrench. You will need a whip and NMO mount, it does not come with a whip or mount. To operate at 136 MHz you need about a 54" whip, for 2 meters or commercial frequencies of course a bit shorter. About 49" for 2 Meters for example. These make a dandy 5/8 Wave 3dB gain antenna. Again this is the NMO Coil, gasket and wrench only, you supply the whip and NMO mount. Bulk packaged.
