TYPE 3° cew car CBW Double Tuned CBT Triple Tuned Frequency Range: IooMHz-240MH2 Quality Features: 0 Good performance in size ratio. - Superior resistance to shock, vibration. temperature and humidity varletlcns. - Ideal for the VHF band. such as CATV, where low inser- tion and very high selealvlty are impcmnt. - Niclcl plated copper shield reduces insertlon 10$ and improves selectivlty. 0 Brass tuning slug for distributed capeciience adjust- ment is a block lorm precisely tilted to a threaded ad- lustrnent screw for very line equatmem. A spring between theblockandhapoilheshleld providesaddi- tional pressure to maintain setting and a constant groundlng path.

Coil form dimensions are precisely controlled through the use of high quality molds during iabricalicn to ac- sure consistent spacing between grooves and a con- stant winding pitch. This produces superior consistency In the winding at the coil. which in turn gives more sta- ble electrical chemciensflcs. 0 Dividing plane between cell iorms is soldered to mairu leln consistent relerence point (window) between res» neiors tor precise coupling. - Coll bobbln and base are formed lrom a specially com- pounded malerial, which promotes low Insertion In” and produces oumendlng stablllty during changes In lemperlure and humidity. - Termlnals lecture rounded ends to lacilltete PCB inser- tion and precoldered lor a reliable PCB connection. - Grounding tabs on cavity simplliy grounding and Im- prove stability.
