Rigid Line Transfer Coaxial Switches
This RLC Electronics’ Rigid Line Transfer Switch provides
extremely high reliability, long life and outstanding electrical
performance across the complete broadcast bands. This switch
is available in either automatic or manual switching in 7/8, 1 5/8,
line sizes. Standard units are normally available in 50 Ohms,
however 75 Ohms can also be furnished. EIA RS225 apply to
all switches.
