I was over today doing some more work at the site, everything is
still online and operating.<br>
<br>
I swapped the LMR400 coax out for 1/2" heliax and grounded it for
one of the business band repeaters today, and remounted the GPS
antenna on a better mount.<br>
I pulled 9 runs of CAT-5 for the data radios and installed a UPS
from home too.<br>
<br>
Granted this doesn't seam like much, but there is quite a bit that
goes into putting in coax. <br>
<ul>
<li>The heliax needs connectors on it which takes about 20 min per
connector to install.</li>
<li>Coax needs to be grounded with a ground kit after it's
installed, and this requires antioxidant compound and cleaning.
Then you have to seal up the jacket of the coax.</li>
<li>once inside the shelter you need to install a lightning
arrestor with more antioxidant</li>
<li>then a jumper of coax is made up and fished in the ladder
racks to the repeater.</li>
</ul>
<p>Tomorrow we will get the grounding done up at the top roof and
some final tweaking of the antennas completed. If all goes well
I'd like to get the 440 and 900 mhz repeaters interfaced to the
computer controller and off the internal controllers. This will
allow us to link them to the 220 and other repeaters once the
internet is hooked up.<br>
</p>
<p>We may be adding a pre-amp to the 440 repeater to see if we can
get it hearing a bit better. The 220 is working well enough to
not mess with at this point. 900 seams to actually be working
well as far as I can tell. We've not heard many people on 900 to
test with.<br>
