## What is RF Haversine Lite?

The RF Haversine Lite (RF Propagation and Analysis Tool) bring our experience gained on Radio Propagation to the mobile market. 

RF Haversine Lite is an application for iPhone and iPad with which you can quickly calculate a radio link budget: 

- Calculate simple radio link budget - between tho locations
- Check the two locations on Map
- Calculate Fresnel Radius
- Calculate Earth Bulge 
- Calculate attenuation loss for O2 and Vapour (Vapour Density 7.5g/m3) 
- Calculate Fade Margin for different radio availability - based on K region (Rain Fall region - ITU-R PN.837-1) 

Option: 
-Email the radio link report and KML file 
-Open KML file in other compatible application 


Full Version:

RF Haversine is the first application for iPhone and iPad with which you can quickly check: 

- Check the Terrain Profile between two locations (elevation provided by a public server) 
- Calculate radio budget based on terrain profile and radio parameters 
- Calculate DIFFRACTION LOSS (calculating only for the first major obstruction from profile) 
- Import new links from CSV 
- You can change the default values for the radio parameters
- For the new links you can use your current location, choose from an existing one (History) or select a point on the map 
All you need - The tool requires an internet connection for terrain profile. 
The Lite Version don't Offers In-App Purchases (You can't upgrade to the Full Version)!


The RF Haversine analysis covers the range of 35MHz- 38GHz. 

No training is required and the grip is immediately.

### 5/5 — Great for use in the field

*2016-01-12*

Easy and pretty good tool

### 4/5 — Alan

*2013-10-26*

Excellent concept.
Would benefit from a help menu.
Would be very nice if the option to use UK grid references as well as lat/long was available.
Would be good to see what K factor (earth curvature factor) is being used (or to allow it to be input).
