Path Calculator is a preliminary link planning tool.
Verification of line of sight and Fresnel zone clearance, spectrum availability, GPS coordinates, and mounting heights should be confirmed prior to network installation.
Please contact a sales representative on further inquiries
regarding link performance.
Note: SAF Tehnika default recommendation is >15dB for fade margin and >99.99% for availability.
