[amsat-bb] Re: IC-821H Frontend Overload?

[Dee]

There is no 24db gain 432 preamp from ARR-They list as a 1 db difference.
You should go for the gasfet as the noise figure will be the difference.  I
used one on my 821H for many years-no probs encountered.

It's all about noise figure....I say get the AR2 SP432VDG 24db!    If
the front end is "too hot" you can use crummy coax to attenuate the signal
;)

Does the 821H have a preamp that you could turn off if necessary?
Probably won't be necessary, but just in case...

better choice?
