HF radio or satellite phone: which is better for remote operations?

They complement each other. Satellite phones like the Thuraya XT-LITE give instant private calls with zero setup, but carry airtime costs. HF radio has higher upfront cost yet unlimited free talking, group broadcasts and total independence from any network. Serious remote operations carry both. Acacia Satlink is uniquely placed in Kenya to supply and integrate both worlds, so ask us to design your communication plan.
