Transmission Line Calc 对比 Flora of Yellowstone 的使用情况和统计数据

Transmission Line Calc allows you to perform several calculations related to RF transmission lines. After selecting from one of 53 different transmission lines, you specify the length and operating frequency. The characteristic impedance and velocity factor of the cable is displayed, and the attenuation (loss) as well as electrical length (in wavelengths and degrees) is displayed. Next, you can specify the impedance (both resistive and reactive) and whether this is measured at the input to the transmission line or the load. The impedance at the other end of the transmission line is calculated, as well as the SWR (Standing Wave Ratio) for both ends. The loss due to the SWR is then calculated and displayed, as well as the total loss. Next, you can enter in the input power, the loss due to the cable as well as SWR is displayed, and the net power out. Supported cable types: Belden 8215 (RG-6A) Belden 8237 (RG-8) Belden 9913 (RG-8) Belden 9258 (RG-8X) Belden 8213 (RG-11) Belden 8261 (RG-11A) Belden 8240 (RG-58) Belden 9201 (RG-58) Belden 8219 (RG-58A) Belden 8259 (RG-58C) Belden 8212 (RG-59) Belden 8263 (RG-59B) Belden 9269 (RG-62A) Belden 83241 (RG-141A) Belden 8216 (RG-174) Belden 8267 (RG-213) Davis RF Bury-Flex TMS LMR-100A TMS LMR-200 TMS LMR-240 TMS LMR-400 TMS LMR-600 TMS LMR-900 300 ohm Tubular 450 ohm Window 600 ohm Open Andrew Heliax LDF4-50A Andrew Heliax LDF5-50A Andrew Heliax LDF6-50A Generic 300 ohm Tubular Generic 450 ohm Window Generic 600 ohm Open CommScope 6 Series Plenum CommScope 11 Series Plenum CommScope 59 Series Plenum CommScope 6 Series Drop CommScope 11 Series Drop CommScope QR 320 Drop CommScope 59 Series Drop Aircell 5 Aircell 7 Aircom Plus Ecoflex 10 Standard Ecoflex 10 Plus Ecoflex 15 Standard Ecoflex 15 Plus Ecoflex 10 Plus HTX MACX350A 3-1/8" Rigid Line MACX450A 4-1/16" Rigid Line MACX650A 6-1/8" Rigid Line MACX775A 7-3/16" Rigid Line MACX850A 8-3/16" Rigid Line

Flora of Yellowstone

High Country Apps is proud to team up with the Yellowstone Forever (www.yellowstone.org) as its conservation partner for its Flora of Yellowstone app. Flora of the Yellowstone Region presents more than 450 wildflowers, grasses, shrubs and trees readily found in Yellowstone National Park and the surrounding national forests of Idaho, Montana and Wyoming, and beyond. Designed for expert and beginner alike, this guide presents each species in a clear, informative format that provides photos and illustrations of the plant, an easily understood description, distinctive field marks, preferred habitats, and tidbits on the plant’s ecology and cultural use. An innovative, easy-to-use key allows the user to select flower color, leaf type, and other characteristics to quickly identify unknown plants. You are on a hike, look down and see a flower with yellow petals and opposite leaves but don’t know its name. It could be tall and thorny, sticky with black berries, sweet-smelling with square stems. Just select what you do know on the app and all plants matching your description will be shown. Photographs and information used by the app are stored locally, making the app available to use with or without a data connection. The Greater Yellowstone Region is a land etched by rivers and mountains, and accented by wildflowers. Its unique plants include diminutive orchids, plants that flower once every 60 years, plants that are a favorite food of grizzly bears, and others that are deadly poisonous. Taken together, their forms, colors and habits are diverse and compelling. Whether you are hiking, camping, enjoying a walk, or just driving through, Flora of the Yellowstone Region is the field guide app to take along. We hope this app increases your enthusiasm for the plants that give us all life and inspiration. Revel in the wildflowers and infect others with your love of the land.
