PDI Communications’ PDI-60CM is a synthesized, SAW filtered, 60dBmV high performance fixed frequency modulator. This unit is manufactured and thoroughly tested, to comply with and in most cases exceed, all FCC recommended parameters. The PDI-60CM provides fixed channel selection for any cable channel from channel 2 through 134 (54-860MHz) plus T-7 through T-12. The PDI-60CM cut channel modulator is available with an extended 3 year warranty for $150.00 per unit.  The extended warranty must be bought at the time of modulator purchase.

$795.00 per Unit - *Plus Shipping/ Handling
* Shipping amounts will vary, depending on size, weight & destination. ALL shipping charges will be invoiced AFTER the order has been processed.
