[time-nuts] Lecia L1 GPS chokering antenna voltage,

[Mark C. Stephens]

Thank you, It is a AT575-90_G!

Now, On the bottom, there is an arrow labelled N.
I presume that is supposed to face north?

I can't tell you how ideal this antenna is for my application, outstanding!


Thank you again.

Hi,

Is the antenna identical to this?

Do you have some pictures of the antenna? In particular the antenna element?

Aeroantennas of this vintage is usually "RG" which according to the spec above 5-18VDC. I recall having seen 4.5V as lower level to.

Modern antennas are usually good to 3.3 or lower. With vintage antennas this is much more uncertain.
