Specs Gain: 4 dBi SWR: 1.5:1 or Less Pattern: Omni-directional Wavelength: 1/2 Elements: 1 Tuned: 452-457 MHz Band: UHF Connector: Your Choice Cable: RG8X Cable Length: 18 Feet Height: 24" Width: 1 1/4" Depth: 3/8" Weight: 1 lb Features Unique Design: This antenna is designed for anyone who's interested in getting good performance on their scanner or radio, but isn't able to use an outdoor antenna. This is a great antenna for people who live in apartments or condos. The Blade can also be used as a travel antenna, or even outdoors for short periods of time.Tuned to Train Data Frequencies: Each antenna is tuned to the center of the North American railroad train data band, between 452.0 MHz and 457.0 MHz. This will cover data packet broadcasts used in various ways onboard trains, such as the End of Train Device (EOTD), Head of Train Device (HOTD), Distributed Power (DPU), and Remote Loco Control (RLC). This will work with any scanner or radio capable of receiving the UHF 400 MHz band. People sometimes use the reception of these data transmitters as a way to get a warning that a train is coming. You do NOT need a digital capable radio. Note: No voice communications are done on these frequencies. Only small data packets will be heard. This antenna is NOT for receiving ATCS railroad system data.Ready Made: There's no assembly necessary and 18 feet of coax (with BNC or UHF connector) is included. (Email to possibly request other connector types.) Easy to Position: The beauty of the way this antenna works, is the fact that you can position it anywhere. Unlike using a rubber duck, you can find the one good spot in the room that gets the best reception, but still put the radio anywhere you like. This can also be helpful if you're trying to move the antenna away from RF producing devices. There's also no ground plane elements sticking out to poke you. The antenna can easily be hung using the two loops on the back.Unobtrusive: The Blade design is very slim and stealthy. The antenna is only 1 1/4" wide and a mere 3/8" deep. It can easily be hidden behind blinds, but is also attractive enough to be displayed in clear view. The antenna's bright white enclosure blends right into the surroundings.Copper Elements: Elements are copper clad, which is a better element material than stainless steel.Narrow Bandwidth: The bandwidth for the antenna is fairly narrow, which can help to eliminate intermod problems from adjacent strong signals in urban areas.18' of RG8/X Cable: This cable is better for longer lengths than the average off brand RG58 cable included with most antennas (if any), and helps prevent signal loss.Direct Feed Point Connection: The coax is directly connected to the antenna elements, which means there's one less connector between your radio and the antenna. Each additional connector can create signal loss.*Blade model antennas are primarily designed for low power.Made exclusively by DPD Productions in the USA
