Using the VSWR Calculator
Convert a known VSWR, return loss, reflection coefficient, or percent return into the other quantities. Optionally add incident power to estimate reflected power, or review a sweep table; calculated values do not replace calibrated measurements….
Using the QIMD Calculator
Screen a repeater channel plan for likely intermodulation products. Check the assumptions and analysis mode, then use each reported coincidence as a finding for engineering review—not as a signal-level prediction or desense clearance….
Using the Feedline Calculator
Estimate coax loss and antenna-end power from cable type, frequency, run length, transmitter power, and connector assumptions. Compare a second feeder and confirm connector loss is included when sending estimates to System Builder; this is a planning estimate, not an installed measurement….
Using the System Builder
Build a preliminary bill of materials from a repeater-system brief. Choose a starting path, confirm the system inputs, and review the ranked components and engineering caveats; the BOM is an intake aid, not a released design….
Using the Coverage Calculator
Estimate RF coverage radius from transmitter power, frequency, antenna gains, receiver sensitivity, feedline loss, antenna heights, and receiver environment. Choose an available propagation model and review its limits; results are planning estimates, not site-specific coverage guarantees….
Using the Antenna Downtilt Calculator
Enter the antenna height, receiver height and the datasheet’s half-power vertical beamwidth to see where the beam meets the receiver plane, or enter a distance to find the required tilt. The result is a flat-earth planning figure with a clearly labelled 4/3-earth check….
Estimating coverage, keeping results and asking Telewave engineering
The Coverage Calculator estimates how far a transmitter reaches from a link budget. Keep a result privately in My results, or attach it to an engineering request so a Telewave engineer can review it. A result attached to a draft request is sent when you submit the request….
Finding products and requesting a quote
Choose a product type, narrow the list with the search box and filters, and open a product to check its specifications. Add what you need to the quote cart from the product page, set the quantities in the cart, and submit your contact details. Telewave usually replies within 1–2 business days….
