The bandwidth on the 25 to 60 MHz element allows the meter to pickup any 54 MHz second harmonic, thus getting a slightly higher reading. The 2 to 30 MHz element frequency response reduces the second harmonic reading because it's out of the element's frequency range. For the very slight difference, no worries. Thanks Rooster.
@@mauriciolopez9344 A great read on accuracy of Bird 43 meters and elements. www.google.com/url?sa=t&source=web&rct=j&url=jmtest.com/PDFs/Calibration-Tolerances.pdf&ved=2ahUKEwj50f6plLDtAhUtGFkFHebeD8EQFjAAegQIAhAB&usg=AOvVaw3kpT3dh_9-yTPNT1onQZzc
Which is also pretty much bullshit as the slugs will work out of band as well, they have no filter or cut off.. so you can use a B slug on 27/28Mhz and will read pretty close to an A and a H series.. so unless you have them calibrated (which it seems no one does) they can work out of band as well..
pretty much same meter, 30uA meter, a simple turret and a sensor (slug) but have you had them calibrated ??? probably not, that's why they read different, some slugs can be 40 and 50 years old and never been calibrated, same with the meter, they need to be calibrated.
Hi, I have a Bird 43 and I just installed a 2500 watt 50-125 meg element. I have a 1000-watt transmitter. The strange thing is that the meter goes completely to maximum on forward and about 250 on reverse. Would this be normal if I had an antenna problem? Or is the element bad?
so which do you believe ?? the idiots will sooner use the HF ones to impress the CB idiots.. but the main question.. Are they calibrated ?? if you don't have the slugs calibrated what does this prove ??

Makes Lots of Sense... that's why the 25 to 60 mhz read slightly less that the 2 to 30 mhz.🤔

Answered all of my questions
I’d like to see a comparison with Bird and Coaxial Dynamics in a Bird 43, l seem to get a substantial difference between the two.
pretty much same meter,
30uA meter, a simple turret and a sensor (slug)
but have you had them calibrated ??? probably not, that's why they read different,
some slugs can be 40 and 50 years old and never been calibrated, same with the meter, they need to be calibrated.
Thanks man I got two birds and I was wondering about the different MHz slugs

Are you using it within the designated frequencies? If so, and it's still behaving that way, it's possible the element is bad
Where can I get these slugs
open your eyes and use google.
so which do you believe ??
the idiots will sooner use the HF ones to impress the CB idiots..
but the main question..
Are they calibrated ??
if you don't have the slugs calibrated what does this prove ??
