Hi Gentlemen, This isn't exactly tower talk...maybe close enough... I have tried several methods to measure *resonance* of a vertical 20m antenna (which will become a multiband trap vertical). In tun
Hi Brian, Thanks for your reply! The 6 or 7 ohms is only the *reactance* reading, not the resistance reading and at this point I am only recording reactance which as you said, should be zero at reson
I've done a lot of measurments of verticals, and I wanted to get the best possible answer for resonant frequency and feed resistance. My 259-B just wasn't accurate enough for this task, (nor does MFJ
Hi Rick, Your method sounds doable and perhaps more accurate than mine....I would have to improvise...no Minicircuits in my junque box hi hi...lots of toroids though. So I'll see what I come up with.
Two things can cause that. Improper adjustment of the 259B's internal controls or external voltage coming from the antenna that upsets the detectors. There is a filter sold for HF that cures most ex
