Bullet™ and Super-Bullet™ Baluns and Ununs are 500/1500 watts PEP rated, purpose designed for portable and stealth installations for all antenna types. Easy to deploy, heavy and sturdy enough to be thrown over a tree limb with ease and robust enough to run demanding digital modes like FT-8/FT-4, RTTY, and PSK31. Buy the Bullet™ balun or unun of your choice and experience the fun of making your own custom antenna with our convenient wire add-on kits. We are sure you will be pleased with the results.
This cable is 50 ohm and 3 feet long double shielded with foil and braid and PL-259 connectors on each end. All the connections inside are soldered and the cable is made of copper conductors with coax having PVC jacket. RG400 is generally useful up to 5000 watts PEP at HF frequencies below 30 MHz. Greater power capability and frequency range than RG-8X, yet similar physical size.
Use for short jumper for Palomar Engineers Noise Filters like CMNF-500-50 or use with Simple Dipole Feed line Choke (SDFLC) to make a 10 turn high wattage feed line choke. Also useful between radio devices such as transceiver and amplifier, antenna tuner, SWR meter, etc.
** Our Customers also used this RG400 Coax to make ham radio common mode chokes up to 5KW PEP
