Alpha Delta 4 -way coaxial switch

{

{ The excellent quality of this project is characterized by a merger with a constant impedance microstrip cavity for the UHF. Wafer commutors with losses are not used, but a solid system with ball bearings. And no uncertainty on which position has been chosen. The positions not used are automatically put on the ground to reduce the noise interactions and the possible discharges. The antenna in a position in or out .. is always protected in both cases! The Arc Plug is easily accessible from the sicche frontal panel 'you can momentary the switch on any surface. Holder the models endure full legal power.  {

{ The VSWR is less than 1.2: 1 up to 150 MHz, and less than 1.5: 1 to 450 MHz for the Delta series with UHF connectors. 
I modelli con connettori tipo N hanno un VSWR minore di 1.2:1 fino a 500 MHz e minore di 1.5:1 a 1.2 GHz.
I commutatori con SO-239 (UHF) are sized for 1500 Watts CW/FM up to 30 MHz and 1000 Watts from 30 to 450 MHz, taking a VSWR less than 2: 1. Full-power VSWR values ​​could distort the arc-plugcartridge. Insulation of 60 dB up to 450 MHz, typically 70DB under 30 MHz. {
{{ {{} the commutators with type N connectors are sized for power up to 1500 Watts CW/FM up to 150 mHz, 1000 Watts from 150 to 500 mHz and 800 watts d 500. at 1.2 GHz {
All models are so low leaks that usually the interconnection cables have more losses of the commutators themselves. {
