Each radio is connected to its own antenna, and each one has a duplexer module similar to these http://www.repeater-builder.com/motorola/mtr2k/cellwave-pd5042-1-vhf-duplexer.pdf
One is for the vhf radio and one for the uhf. --- In [email protected], Brian Raker <brian.ra...@...> wrote: > > On Thu, Aug 13, 2009 at 4:29 PM, Christopher > Hodgdon<chris.hodg...@...> wrote: > > <SNIP> > > I do have access to a "radio house" located at our high school football > > field and it has two MTR2000 in it, plus two different antennas.
