DELTA-4B has excellent channel isolation  Time owned: 6 to 12 months
We recently changed out the coax switches at our HF monitoring site to the Alpha Delta DELTA-4B coax switches. What a difference! The co-channel isolation is greater than 60-70 dB (as measured here) and the positive switch detent for rotation is very firm and you know where you are.

We like the fact that the surge protection module is replaceable from its front panel. The low in-line loss is very impressive. Hardly measureable until about 400 MHz, but then N type connector units are available. They are built like a tank too. Good going Alpha Delta
