2023-F-020 | HexBeam Balun

Function

On the coaxial cable side an SO 239 connector is provided, while on the antenna side a 30 cm long “pigtail” with PL259 is installed that connects directly to the HexBeam connector. Because the transformer is based on a toroidal ferrite core, the common-mode choke impedance obtained is several times higher than what’s achievable with the standard “string of beads” solution often offered with a HexBeam antenna.

The general mechanical and electrical specifications of this variant are similar to those of a standard Line Isolator.

Mechanical Characteristics

• Optimized 61 mm diameter toroidal ferrites
• Heat resistant teflon coaxial cable with high breakdown voltage.
• Professional 50 Ohms N-connector or SO239 connector. (IP66 after sealing with self- vulcanizing tape or equivalent).
• Waterproof (IP64) and shock proof polycarbonate UV resistant enclosure. More info.
• Weight: +/- 500 g.

Electrical properties

• Deployable frequency range: 7 to 55 MHz.
• Maximum power: 6000 W PeP (ICAS) / 3000 W PeP (CCS) (@ antenna VSWR of < 2/1).
