I have been granted a variance for 57ft of tower and antenna, not bad
considering the town zoning permits no antennas of any kind. I am going to
put up a Tashjian/Tri-Ex LM-354 with an OptiBeam OB11-3 mounted 3ft above
it.
The downside is that in a compromise with the zoning board I agreed to clear
a metric buttload of virgin forest and position the base of the tower about
190ft from my operating position.
I am considering a Yaesu G-2800DXA rotator. Although I could probably get
away with a G-1000, and save some dough, the OptiBeam is .84m/9sqft,
27kg/59.5lbs, with 6.25m/20.5ft of turning radius.
Considering the distance from the operating position to the rotator, which
we will say is 245ft, I am open to wiring suggestions and vendor sources?
Will the pins on the Yaesu end plugs accept larger gauge wire (like 14 or
12AWG)? If I understand correctly the 2800 comes with 40m of wire
preassembled, should I order spare plugs ahead of time, or splice in larger
gauge wire a short distance from either plug end?
Has anyone measured the maximum amperage these rotators draw down,
schematics show the transformer in the controller for the 2800 producing
26V/3.5A but I could not find a detail on the current demand from the motor.
Perhaps the Yaesus are non-starter at these distances and someone would
suggest a different rotator, keeping cost in mind?
And on a side note; is there any significant advantage to using 9913 coax
over RG-213 at these lengths when operating at 10-20m frequencies?
Thanks for any insight.
Peace
