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. 73, Dee, NB2F

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...
