Nav Beacons - How many / How Dense?

[Ian Boys]

I'm not at all sure that Viikate's map shows them all. We know from Karayastaffel etc that individual airfields had their own homing system, I'm guessing that the pic shows the night fighter beacons.

I can't imagine that Ju-52's flying supplies in to Kurland had no beacon to guide them, for example, I'm betting there were beacons at Windau and Libau at the very least.
