Measurements via MFJ-259B

Reviewer: A viewer from W8LM -Wichita, KS

I measured 0.405 uh to 0.815 uh on a MFJ-259B Analyze. The specified 0.676uh value would be nominal mid-range. These coils are adjustable with a standard hex ferrite slug.
use frequency calculator at
http://www.whatcircuits.com/lc-resonance-frequency-calculator/
to calculate resonamce... This coil will resonate in the 20 meter ham band with 200pf cap...
Given that. A hand full of these and some caps would make a tri-iplexer for a triband beam.

.676 slug tuning range

Reviewer: A viewer from Seattle area

I got values close to what W8LM got. i useda 565pF measured cap (Fluke 189 DMM) and put the cap in parallel then used my AIM4170C analyzer. Adjusting the slug gave me ranges of about 0.4 uH to 0.8 uH also. Dennis KB7ST

Actual range

Reviewer: A viewer from Maryland, US

Not sure why these are listes as '0.676ÂµH'.

Using an LCR, they read a range of about 8.6ÂµH to 9.0ÂµH.
