Have your PA9X’ HF common mode choke built

Don’t want to make a broadband common mode choke yourself? I will gladly build one for you to buy. By the way, did you know a common mode choke is also often called an RF line isolator, 1:1 balun and 1:1 unun, Latter two for transforming a (un)balanced antenne to an unbalanced feed line.

Specs

Frequency range: 1.8-30 MHz (160 m to 10 m band).
Common mode suppression: 25 dB around at frequency range edges to 45 dB at 14 MHz.
Power rating: 1000 W SSB | 500 W CW.
SWR: <1.1:1 from 1.8-30 MHz.
Case: Weatherproof plastic ABS IP65.
Sockets: 2x SO-239 PTFE female.
Size: approx. 12 x 8 x 5.5 cm.

Need more power (up to 2 kW SSB)? Different connectors? Specific for low band (0.1-30 MHz) operation or low VHF (30-70 MHz) operation? I can do it!
