Difference between DRPE4-6V(L) and DPRH4-6-2M:
This duplexer has no thermal compensating screw made of Invar®, as distinguished from DPRE and DPR professional duplexers. But it makes no difference if a duplexer is located in a heated space. A thermal drift of +/-15 degrees does not affect the operation of the resonator. Therefore, such solution helps to reduce the duplexer costs.
