Alpha Delta Coax Switches have a precision-machined switch shaft and quadrant mechanism for more accurate and stable switching performance.

These switches have a low-loss micro-strip cavity design, positive detent switching, master antenna ground function, a front panel removable arc-plug surge protection module, and excellent HF through UHF performance. The unselected antenna ports are grounded for protection and maximum isolation. Rated through 500 MHz. 0.10 dB loss to 30 MHz, less than 0.5 dB through 450 MHz.

Alpha Delta Coax Switches are used worldwide in government, military, and commercial applications and are manufactured in Alpha Delta’s ISO-9001 certified production facility in the USA. They come available with either a 2-port or 4-port position, and both have the option of either the UHF female (SO-239) or N female connector.

These switches are all built into the same heavy-duty chassis that is 5.250 x 3.500 x 1.250 in. (WHD), excluding connectors and knob.

Note: When placed in the “COM” position, all switch positions are grounded. When a port is selected, that port is ungrounded while all other ports remain grounded.

Additional features include:

* Higher strength, lower resistance silver bearing solder
* Durable abrasion resistance with powder-coated finish
* Brass arc-plug housing for improved gas tube positioning
