Overall
Review of ALPHA DELTA ASC-4B
Review by KO6EHY
The Alpha Delta ASC-4B is a premium 4-position desktop antenna switch that justifies its higher cost with superior build quality and features.

Solid construction: Heavy powder-coated steel housing with non-slip feet—feels military-grade and stays put on the desk.
Smooth, precise switching: Precision-machined mechanism for reliable performance at full legal-limit power (up to 1500W).
Extra connectivity: 4 antenna ports plus built-in solid brass ground bus bar (#10 wire points) for easy single-point grounding and reduced RFI/ground loops.
Surge protection: Includes field-replaceable Arc Plug lightning protection for added safety.
Excellent specs: Negligible insertion loss (<0.10 dB), high isolation (>60 dB at HF), all ports can be grounded.

If you're upgrading from flimsy switches, the ASC-4B delivers pro-level reliability and convenience. Worth the investment—buy once, cry once.
5 stars! Highly recommended for serious operators.
