My SGC-237 is hard to mess up. Where ever you attach the wire to the
tuner is the beginning of the antenna. The coax attach will simply be
a matched line to the transceiver. I would be inclined to simply
attach the coax to the inverted V as you outlined and use it.

The antenna is in an environment that will not model well. The
radiation from the coax will have an effect on the aggregate
performance but nothing you can really measure.

Although I doubt anyone can explain just how it works, the SGC-237 and
the wire you have described will work fine.

Modern antenna tuners perform a lot like Magic in my estimation.

My own feeble experiments have led me to believe that it is worthwhile
to put an antenna analyzer on the configuration and make sure that the
array is NOT resonant on any frequency of interest. The tuner seems to
like that best.

Power supply: I have a very old telephone power supply tweaked down to
12 volts. I leave it on 24/7.


Thanks for the feedback, John. I imagine that we will end up doing
as you suggested. We WILL test the antenna on the ground with a
temporary mast to see if there are any issues, but we also realize that
things can, and probably will, change when it is permanently mounted on
the building. One of the reasons I am posing these questions here now
is that once the antenna is up, it will be difficult to get the
building personal ( its a firehouse ) to lower the mast for changes.
Its a rigid one piece aluminum mast that will be bolted at its base to
the building.
