I have both the mast mounted and in-shack 2 meter and 70cm versions.
Normally they work well, but one word of caution, if you use them for
full duplex satellites, best to get the older versions that are in an
aluminum cast box. This reduces cross talk when transmitting on 70cm.
The new versions are not shielded, at least the one I had and got rid of
it. The new ones were in a plastic box, no shielding, and a simple
stainless steel angle bracket for mounting. All the ones I presently
have are the aluminum boxes. You might want to call MFJ and confirm the
present day construction. Otherwise, I found them to work well and will
operate with voltage sent up over the coax. Also, they can handle 160 watts.
Also, the newer external voltage box to supply the preamp are kind of
hokey as well. They use to use a very nice square aluminum box, then
went to a plastic box that suppose to sit on your table. However, the
RG-8 or whatever coax makes this not very practical.
If not used for satellite full duplex or in simple single band
operation, the units should work okay.
