Allow me to clarify my post. I was referring to the high impedance
amplifiers at the vertical elements, not the 2N5109 preamp used
sometimes post combiner.

As an alternative to the 2N5109 preamps, last year I acquired a set of
HiZ preamps to use on my YCCC 9 Circle array elements. They work
exceptionally well and exhibit a lower noise figure that I experienced
with the original YCCC amps.
I mentioned this solely for information with no other purpose as I
realize some like to use a simpler amplifier design that they can
build and/or repair. If you have an interest other than what has been
mentioned you can contact Lee at HiZ.
