Tuned Coaxial Choke 3KW, 7-21 MHz, 4K+ Choking, High Duty Cycle
3000 Watt PEP Rated 1:1 Tuned Coaxial Feed Line Choke™
This higher power BALUN or UNUN utilizes mil-spec coax cable for the windings The dielectric has insulation for high voltage ratings of 1,900 volts. Available wired as a BALUN (TCC-40B) with +/- output terminals or as a UNUN (TCC-40U) with PL-259 input and output connectors. Frequency range of 7-21 MHz, centered on 12 MHz.
Excellent for all vertical antennas and many others in harsh environments where a tough choke is required to withstand the elements. If you run RTTY contests at 1500 watts output, this is the balun/unun you need – it won’t burn out at heavy 1500 watt duty cycles like other brands rated at 1500 watts (or more). We use these same chokes in our own RTTY station at full 1500 watts output and they have never failed.
