Hi there,
something about the power supply. If it's an older Leica choke ring antenna,
it uses an AeroAntenna antenna element. Perhaps there is still a label on
the lower side of the choke ring.
L1L2 antennas had the part number AT2775-..., L1 had been AT575-...
The power supply is coded there.
AT2775-20W-xxxx-xxx-xx-xx-xx
| | | | +--- magnet (if available)
| | | +------ antenna gain (00=passive, 12=12dB ...
| | +--------- supply voltage (00=passive,05=+5V,RG=+5..+18V
| +------------- cable length [inch]
+------------------ connector type
... same with AT575.
Best regards
Martin
