The excellent quality of this project is characterized by a merger with a constant impedance microstrip cavity for UHF. Wafer switches are not used with losses, but a solid system with ball bearings. And no uncertainty about which position has been chosen. Positions not used are automatically grounded to reduce noise and possible interactions is low. The famous Alpha Delta Arc-Plug ™ Cartidge protects the location. The antenna in or out. It's always protected either way! The Arc Plug is easily accessible from the front panel so the switch can be mounted on any surface. Both models bear the full legal power.
The VSWR is less than 1.2:1 up to 150 MHz, 450 MHz and less than 1.5:1 in the DELTA with UHF connectors.
Models with N-type connectors have a VSWR of less than 1.2:1 up to 500 MHz and less than 1.5:1 to 1.2 GHz.
Switches with SO-239 (UHF) are sized to 1500 watts up to 30 MHz CW/FM and 1000 watts from 30 to 450 MHz, assuming a VSWR of less than 2:1. Higher values of VSWR at full power could distort ARC-PLUGcartridge. 60 dB isolation up to 450 MHz, 30 MHz. typically 70dB below
Switches with N-type connectors are designed for outputs of up to 1500 watts CW FM up to 150 MHz/1000 watts from 150 to 500 MHz and 1.2 GHz 500 to 800 watts d 1.2 GHz, 1.3 GHz not footnote:. 60 dB isolation up to 500 MHz and 50 dB from 500 MHz up to 1.2 GHz. In the case of a VSWR not bigger than 2:1.
All models are so low that usually interconnect cables have more leaks of the switches themselves.
