- Us history majors sometimes need to ask elementary questions, so please be kind. Yesterday I was refurbishing my 80M lazy-vee dipole array, measuring the center frequencies to adjust as needed. On my

- no, that means something is wrong. there should always be a point where the reactance crosses from inductive to capacitive and goes through zero. I would guess that you are getting AM broadcast inter

- Pete, Does your MFJ 259B separate out reactance and provide the sign (complex R+jX rather than only Z magnitude)? I thought some MFJ models only read magnitude of the impedance. If the 259B reads com

- Hi Paul - no, the MFJ does not give you the sign, just R and un-signed X. 73, Pete N4ZR Check out the Reverse Beacon Network at http://reversebeacon.net, blog at reversebeacon.blogspot.com. For spots

- Looks like everyone covered that you need to know the sign (capacitive/inductive) as well as the magnitude of the impedance. Here's a brief tutorial that shows what happens to an impedance as it is t
