I belong to a volunteer emergency comms club. We're about to install permanent (we hope) antennas on the roofs of 24 reception centres. In the event of a mass evacuation of the City or parts of it, folks will be going to these centres where they will be registered and their needs determined. The only communications between these centres and the City Emergency Ops Centre in the event of failure of the normal comms infrastructure will be via ham radio using these antennas. They'd better work.
We want to thoroughly document each installation and set up a maintenance schedule whereby each antenna will be swept using our brand new 4170 on a periodic basis in order to check for degradation of the antenna system. i.e. improving SWR will tell us we'd better check the coax loss against what it was when first installed.
I'm in the process of creating a form for documenting each installation and am wondering if anyone here has already done this and is willing to share their form with me.
The idea is to document everything about the installation so that, if maintenance is required, the form will show make and model # of everything, length of coax runs, if a feedline comprises two or more lengths of different coax, what connectors/adapters are used, what tools and their sizes are needed to disassemble/reassemble stuff, how things are mounted, etc.
In other words, if one of our volunteers has to go and do some antenna work, he'll know ahead of time exactly what he's facing and what he'll need to take.
Can anyone help with this?
