Hello,
I tottaly agree with Ted, i have a single moxon (not turnstile) for VHF LEO
satellite and works quite good. Also i have another, a moxon turnstile for
436 LEO satellites and it work relatively fine, but average gain is only
good enough for SSB satellites. For FM reception a good LNA is mandatory.
Right now i don't have any LNA neither for VHF or UHF (that's why I always
work AO-27 with my arrow antenna). I can tell you that even a single moxon
is almost enough, at least for VHF, for UHF the signal loss is greater so
the incoming signal is not enough for FM, but i can at least hear and see on
the FFT spectrum display any SSB or CW, they usually show up with at
least10dB over the noise background.
The moxon are greats but a good LNA just after the antenna will be very
helpfull. One more thing, for a smoth recieving pattern is better to put the
antenna close to the roof, this avoid the nulls and fadings but compromise
the reception at low elevation angles.
Well, that's all. Just my little experience with these great antennas.
Good Luck all,
73!!!
Raydel,
