411C Series Failsafe/Latching
The DowKey
¨
Microwave 411 Series is failsafe or latching transfer switch for use in applications were high isolation, low VSWR and low insertion
loss are critical. The DowKey
¨
designed connector features a mechanically captivated center conductor which eliminates epoxy staking, and
consequently, RF leakage. Typical Applications: Switch matrixes, standby transmitters with dummy load and alternate antenna select.
