I have a new LM354HDSP crankup tower. I got the tower up, back in late
November. That is where the project stopped for the winter. All it is holding
up is an inv vee for 80 mtrs right now.
The antennas are a 4el SteppIR and a Cushcraft XM240 on a chrome moly mast.
Nothing is installed yet.
I purchased a Yeasu 2800DXA rotor to turn it, but now having second thoughts if
the rotor will handle it long term. The "K" factor is 85% of the published
rotor rating.
I called Yeasu and they told me to take the weight off the rotor. They
suggested adding a second plate and bearing between the rotor and tower top
bearing, and take the weight off. Sure did not come away with a warm and fuzzy
feeling that the rotor would handle the load.
So I am taking pause and sort of rotor shopping. I realize I would take a hit
selling the Yeasu. I would rather be safe than sorry later.
I was looking at the M2 Orion 2800 (rotor only) and a Green Heron controller.
Will the Orion fit in a LM354HD top section? I called Tashjian and they could
not answer that.
