T03KO B - Communications & Power Industries

250 W CW Outdoor TWT BUC
Plays in the Rain
Rugged, compact and lightweight high power BUC designed
for outdoor use.
Cost Effective and Efficient
Mounting at the antenna improves performance through
minimized cable losses and saves cost in system design.
Employs a high efficiency helix traveling wave tube, reducing
operating costs. Includes integral block upconverter.
Simple to Operate
