4CX15,000A/8281
The 4CX15,000A/8281 is intended for use in audio
or radio frequency applications. It features a
new type of internal mechanical structure which
results in high RF operating efficiency. Low RF
losses in this mechanical structure permit opera-
tion of the 4CX15,000A/8281 at full ratings up to
110 MHz and at reduced ratings to 225 MHz.
