Not so sparse that the Germans didn't resort to a series of genocides to depopulate the land and "better" it for white settlement. The "Native Problem" won't go away even in Namibia.
Namibia's got prime prospects as a settler colony, and given that it isn't nearly as politically-sensitive as the matter of a Middle Eastern Israel, it's unlikely that a Namibian Israel (which for all intents and purposes would be highly dependent upon British support) would face the same restrictions against Jewish immigration that Mandatory Palestine did.
The blacks of Namibia are also not the most homogenous bunch, tribal loyalties are more important than national ones at the point in time we're talking about, divide-and-rule would be an easy feat.
Irony of ironies: So we hear your people suffered genocide at the hands of the Germans so here's some empty land that used to belong to some people who suffered genocide at the hands of the Germans.
I didn't think of that!
Another less likely or viable, but nonetheless interesting thought is the Angolan coast. The interior which is jungle would be of no interest, but the Mediterranean-style coastline with bountiful resources could be of great interest to settlers.
The only matter would be getting enough settlers to reach critical mass and not make the Jews a tiny minority.
