DadehLink — Microwave Link Calculator

Short Description (80 chars):

Professional RF link budget & antenna calculator for telecom engineers.

Full Description:

DadehLink is a field-grade tool built for microwave and wireless link engineers, network designers, and RF technicians who need accurate, fast calculations without digging through spreadsheets.

Core Features:

• Link Budget Calculator — Compute path loss, received signal level, fade margin, and system gain for point-to-point microwave links across common frequency bands (5 to 18, 23, 38 80 GHz and others).
  
• Antenna Gain from Diameter — Calculate parabolic dish gain from physical dimensions and frequency, with support for custom feed efficiency (η).
  
• Weather & Rain Data — Regional climate data with rain rate lookup to estimate rain fade attenuation per ITU-R models.
  
• Alignment & Compass — Built-in azimuth and compass tools for on-site antenna alignment.
  
• Map & Distance — Apply link distance directly from map, with location-aware tools.
  
• Qibla Direction — Included as an on-site utility.
  
• Save & Restore — Store up to 30 previous link calculations, with four-per-page browsing.
  
• Secure Login & Updates — In-app update checks and protected session storage.
  

Who is it for?

Telecom contractors, RF planning engineers, field technicians, and network operations teams who work with licensed microwave bands in daily field or office use.
