Mini Kits Australia make a very nice 2m switched preamp, 100W CW
non-sequenced, 500W when used sequenced.
Mark has a new version which uses the PGA103 mimic. I have two of the
previous version and they work very well. One I use for VHF
roving/portable use and the other is mast mounted. They do need to be
put in an enclosure of some sort and Mini Kits sells a nice enclosure
that fits nicely and is not expensive. I put mine in Hammond 1590WBBFL
10 to 18 dB gain (adjustable) 0.8db NF
Mark is great to deal with, shipping is reasonable and quick, and the
exchange of US$ to AUS$ is attractive.

At current exchange rates, these are roughly the same price as the ARR, and considerably cheaper than some other mast-mount alternatives. The IC-9100 powers them through the coax without the need for any other supply.
