<< The scenario: Building is all concrete, steel and rebar, and handheld
operation is desired from anywhere to anywhere in the building. VHF on a
simplex channel is about the only way we can go.
My solution: A combination of passive radiators, and Radi-ax. The passive
radiators on each of the housing units, and Radi-ax running through the
floors and ceilings in Administration areas. >>
Is Radi-Ax a feedline? I'm not familiar with it. The way most indoor
systems are done is to use 'leaky' coax; that is, coax with the shield cut
away a lot. The inner conductor can then radiate. This is popular in tunnels
as well as buildings.
