This high end, high quality broadband HF and CB (27 MHz) common mode choke (1:1 balun / 1:1 unun) prevents common mode noise and RFI in your shack and your neighbor's electronic devices. It also let's you connect your symmetric (e.g. dipole) and asymmetric antenna (e.g. vertical and EndFed) to an asymmetric feed line. Thus improving radiation efficiency.

Recommended for use with antenna types like vertical, dipole, Yagi, EndFed, G5RV, ZS6BKW, inverted V, Cobweb, Hexbeam, Windom (OCF) and Doublet. And typical CB antennas like 1/2 GP,  Antron 99 and iMax 2000.

This choke has a larger bandwith and is more effective than versions with coax windings over a toroidal core. The suppression of common mode currents (that travel on the coax' outer shield) is approx. 25 to 45 dB from 1.8 to 30 MHz with SWR below 1.1:1.

Genuine Fair-Rite toroid. Wiring is 600 Volt PTFE insulated.

In weatherproof UV stable plastic rainproof IP65 housing of approx. 12 x 8 x 5.5cm.

SO-239 UHF female socket on one side, PL-259 male connector on other side.

Color of wiring may vary.

Maximum power, approx.:

1000 W SSB | 500 W CW | 200 W Digi

User and installation tips are included and you get my full personal and lifetime support.

For a 2000 W SSB version, please see my other objects.

Internationally shipped with track & trace.

Handcrafted by PA9X.

Be careful with baluns and common mode chokes without a picture showing what parts are actually inside. Same with claims over 1 kW on a single toroid.
