[Antennas] schematic needed for Collins 180L3 ant tuner

[Alan C. Zack]

You may find it by searching for the Collins 618T Txcvr (Military name
AN/ARC-94).  The 180L3 or the 490T are the tuners that this txcvr uses to
match to the antenna on the aircraft.
I'm trying to remember if the old ARC-38 txcvrs used the 180L or if it had
a built in ant tuner.
We used ARC-38's in our HU16E acft and 618T's (ARC-94) in our C-130's and
H52A Helos.
