Finished high quality short wave SSB communication network connecting space of the oases in Sahara

摘要

We installed SSB HF communication network system using The shorten hot end feeding 1/2 λ wire antenna(Trade name Zepp type wire antenna) at Mauritania in West Africa with one point frequency 7.8315MHz and could always communicate stability at any time with the office to any stations in oases at close range but also up to a range of 1000km. We could communicate with such radio stations from a mobile equipped with a 70cm long roof side whip antenna clearly while running through the rough course of the Paris-to-Dakar Rally. We will report in details a how we finished such a high quality 8SF HF communication network system so successfully by The Zepp type wire antenna and 70cm roof side whip antenna.
