Without seeing the picture your referring its a little hard to say exactly what HF equipment they are using but depending on the specific African country it can be anything from current commercial product to modified amateur and military surplus equipment sourced from any country fighting, supporting or sponsoring conflict and aid over the years.

You will also find that a large number of the countries have spectrum management authorities and band plans but as has been discussed, being government run authorities their function and efficiency varies greatly. The only guarantee is it will be a slow and expensive process to navigate.

Two very common brands used by Safari, Government and NGO's is Codan Limited and Barrett Communications both Australian companies.

From their commercial product ranges;

Codan radios typically NGT / Envoy series radios and 9350 / 3040 automatic tuning mobile antennas.

Barrett radios typically 2000 series / 4050 radios and 2019 / 2018 automatic tuning antennas.

Many of the safari and tour companies run their own company frequencies (base to base, base to mobile, mobile to mobile) but also have access to various agencies, government and NGO depending on the country or area.

You will find very similar HF equipment, networks and inter agency arrangements in Australia, Papua New Guinea, Mongolia, Pacific Islands, New Zealand and a number of the smaller land locked Asian countries as well.

Australia and New Zealand particularly are well served by a number of nationwide HF networks for the touring and 4WD communities using frequencies typically spread through 3.0 -14mhz ranges USB 100watt P.E.P offering AVL, analogue voice and telephone interconnect. Network usage is generally by annual membership and letter of authority to operate.

The technologies in use globally include analogue voice and data, digital voice,hf email and fax, telephone interconnect, frequency hopping, ALE, AVL etc.

Been a loyal Codan radio owner user for near 30 years myself.
