The antenna arrived sooner than I expected it, fit perfect on my NMO 2 meter mount and tuned with a bit of cutting to the mid CB (11Meter) band. I am very happy with the easy conversion between both ham and CB use.
This Larsen CB antenna with the NMO mount fit perfectly on my 2 meter 70 CM mount. allowing me to swap out my ham radios for CB by just using my MFJ meter to tune up.
Some times a good CB radio will get you of trouble when a ham rig won't.
Thanx CB World. I got exactly what I ordered, when they said it was going to be delivered. Good price, good quality product. As advertised, new, sealed in packaging, and shipped in a box with extra stuffing as not to rattle around during shipping. The Low Band Antenna tuned up perfectly the fist time using a Bird slug. You can't ask for better than that.
