Accurate. Convenient. Powerful

Keyhole Radio Google earth RF planning


CloudRF is next generation RF planning software. There's nothing to install but you get premium features you'd expect from a desktop package including global high resolution terrain data, customisable ground clutter, radio templates and 3D antenna radiation patterns. Everything is calculated using powerful servers and stored in your own archive so you can get at it anytime to download it or share a link. The SAAS service can be used via a wide number of client interfaces for mobiles, web browsers, Google earth™ and even a custom API. We're constantly innovating new features and improving the software using feedback from amateur and professional users.


The easy to use software covers the RF spectrum from 20MHz to 100GHz spanning VHF, UHF, SHF, EHF with generous height ceilings and distances for aircraft, large power limits for long range TV broadcasters, cellular propagation models for mobile technicians and environmental variables to accommodate suburban, rural and mountain planners alike. The empirical and deterministic models available are applicable for any user of the RF spectrum and the multi-mode interfaces are simple enough for novices with advanced features for professional users looking to optimise a site's footprint.

We use open source software to keep costs down so you only pay for what you use beyond 10km radius with prices starting at USD $2.5 for 250 planning credits. 250 credits will let you run ten 25km calculations or a single 200km calculation (with change).
Small calculations under 10km radius are free
