1. -nn in model number represents the number of channels.
2. Consult factory on T-Pass multicouplers for frequencies below 215 or above
300 MHz.
3. Models available with 5W/60W loads. Same specifications as 25W and 100W
models, except load power.
4. -MC option reduces maximum number of channels to ten 10-inch or twelve
6.625-inch channels per rack.
5. -LR systems are tuned and tested on customer frequencies, then disassembled for
shipping.
6. Rack depth with cavity tuning rods at maximum frequency. Rod travel is
approximately 3.9” (99 mm).
