I have buile ONE demi preamp -- 2.4GHz as I recall. Well designed, OK to put together (doable, but must be patient and careful -- probably less of an issue at 2m).
Performs very well.
You could do worse than a demi kit.

SO...now I have made a few contacts on AO-51 and SO-50. Now I need to get better ears.
I have a very simple mode J setup using a couple of old mobil rigs--the rx unit is an IC 2350H. 10 el cheap yagi through 60ft of LMR400.
I'm considering options for a mast preamp for rx only. I'll be using a diplexer for desense ahead of it, and eventually add coaxial switching so I can use TX.
I'll feed with power through extra wire in rotor cable.
Looking at the Hamtonics, DEMI kit and a hombrew from scratch.
Any experiences with the DEMI units as kits?
with there relatively high NF, are the MMIC devices like the ERA
series, at all appropriate for simple mast preamps for entry level application?
Thanks to all.
