CUBE 1:1 Balun, 5KW, 160-6 Meters, -38dB CMRR, FT8/RTTYProduct DetailsBrand: Palomar EngineersEffective Frequency Range (MHz): 1-61 MHzPEP Power Rating (watts): 5000Estimated Insertion Loss (db): .10Input Connector Type: SO-239 femaleOutput Connector Connector Type: top studs or side eyeboltsGround Connector (Y/N): noneEnclosure Size (LxWxH inches): 4 x 4 x 45000 Watt Rated 1:1 CUBE™ BALUN
* Suppress radiation from coax cable
* Provides maximum transfer of RF to the antenna.
* Help keep RF out of the shack.
* Heavy Duty Cycle for Legal Limit FT8/RTTY
* Reduces RFI to appliances and neighbors.
* Side Eye Bolts or Top Studs Output Option
This BALUN utilizes mil-spec coax cable for the windings on multiple ferrite beads with coax silver shield and silver braid for low loss. The dielectric is Teflon® insulation for high voltage ratings of 1,900 volts. (A typical 5KW signal at 50 ohms impedance will have a voltage of 500 volts at 1:1 SWR). Available wired as a BALUN (CB-1-5000) with wire studs output or side eye bolts for dipole antennas. Rated 5KW PEP/1500 Watts AM/RTTY/CW/FT-8 from 1.8-61 MHz. Enclosure is 4" x 4" x 2"
If you run FT8/RTTY contests at 1500 watts output, this is the balun 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. We use one at the amplifier output and another at each antenna feed point. Works very well on OCF antennas below the 4:1 balun to keep RF current on the antenna and off the feed line. Built like a tank, works like a charm, and priced under the competition – what more can you ask for? THIS IS OUR MOST POPULAR 1:1 BALUN!
