They're commonly available on the internet and at hamfests at discount prices.

It requires more cores to shift the res freq down. _________________ Topband Reflector Archives - http://www.c; /archives//html/Topband/2018-03/msg00167.html (7,216 bytes)

If you are going to build a 160M CM choke, you may as well do it right the 1st time.

Re: Topband: 160M Balun (score: 1): Author: donovanf@starpower.net; Date: Fri, 30 Mar 2018 13:29:37 -0400 (EDT); Hi Peter, What you need in a common mode choke is adequate resistive component to absorb common mode signals as heat. The choke doesn't need to be at resonance to achieve adequate choking resistance,; /archives//html/Topband/2018-03/msg00173.html (10,069 bytes)

If one really needs that a parallel resonant LC circuit can be formed with a normal choke and a capacitor. On my 160m dipole the chok; /archives//html/Topband/2018-03/msg00181.html (10,910 bytes)
