Hi:

Does anyone have any document on the Collins 490T-3 Coupler? I do have a
manual on the 490T-4 but it is a bit different. The 490T-4 was really a
line flattener and the 490T-3 was for actually coupling with an
unbalanced antenna directly. I am now the proud owner of a the 490T-3
and it appears to be in very good shape.

I know it is designed for a 1 KW continuous mode and also requires 115
VAC/400 Hz. It also requires at least 200 watts to provide effective tuning.

Any help would be great.

Thanks.

Kevin

PS: If you have any information on the Collins DC to AC inverter - model
426T (), it would be great.
