Model CB-6-1500 is a 6:1 (300:50) voltage balun housed in a Nema enclosure box (4″ x 4″ x 2″) with two top studs capable of input power levels up to 1.5KW PEP/500 watts continuous when used with a matched load. The 6:1 ratio takes 50 ohms input and matches to 300 ohms balanced output from 1.8-61 MHz with SWR < 1.5:1 under matched load conditions. A great balun for windoms, OCF antennas >60 feet over ground, Hertz and folded dipole antennas, T2FD etc. Dual core, Ruthroff style balun. Choose version with side eye bolts for wire attachments for OCF dipole use.
RG-400 Coax Jumper Cable with PL-259's on each end - 3 feet, Double Shield, High PowerProduct DetailsThis 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
