Work 2m / 440 with Diamond's Super Gainer antennas. The radial-less design works well virtually anywhere on a car body without effecting VSWR.
Diamond Antenna's Supergainers are premium mobile antennas designed for durability and as the name implies, super gain. They use a radial-less structure on both 2m and 70 cm bands so they work well nearly anywhere on a car body. It can be located on the trunk lid, roof, gutter, or any place without effecting VSWR characteristics.The SG7500 utilizes a high performance C-Load (capacitive loading) structure for both bands, allowing for a shorter, more compact antenna.
The fold-over is an excellent feature for getting your rig into or through a low-clearance area without damaging or breaking off your antenna.
Both the 2 meter and 70 centimeter band can be transmitted or received simultaneously, or one band can be transmitted while receiving another band or vice versa, simultaneously by using a duplexer.
They come factory pre-tuned, so no adjustment is needed. If center frequency of the antenna needs to be adjusted loosen the two set screws at the top of the tiltable whip section and adjust the element in or out to obtain the best VSWR at your desired frequency. Just remember to tighten those screws back up when you're done.
