The 4CX20,000E is a ceramic/metal power tet-
rode intended for use as a VHF power amplifier. It
features a type of internal mechanical structure,
which results in rf operating efficiency. Low rf
losses in this structure permit operation at full rat-
ings to 110 MHz.
The 4CX20,000E provides high gain in FM Broad-
cast service and is also recommended for rf linear
power amplifier service, including IBOC digital
transmission. The anode is rated for 20 kilowatts
of dissipation with forced-air cooling and incor-
porates a compact, highly efficient cooler of new
design
