Hi gang,
This could be a good opportunity for someone looking to put up a MonstIR
soon, especially if you are close to Michigan...
Our student club's (The University of Michigan ARC) tower project has hit a
major stumbling block and we must sell our new and never installed Rohn 55G
tower and MonstIR antenna system. To make a long story short, after an
initial "go ahead" was given for our proposed system, an engineer corrected
an erroneous axial load profile and we were told that our roof will not
support the tower/antenna system. Unfortunately, this error was found after
we had already purchased our hardware. We are now working on a smaller
system, and in the mean time, must liquidate the equipment we have already
purchased but cannot use. If you know of someone looking for the hardware
listed here, please pass along this information.
Some good deals are possible for someone who buys multiple items and can
pick them up. Please contact me with any questions at all. My email
address is cgalbrai@umich.edu and my telephone number is (734) 678-2779.
Note that the buyer is responsible for the shipment of any of the items.
Pick up is preferred, but we will do our best to help arrange shipping via
truck. Our building does have a loading dock. All of the equipment is
located in Ann Arbor, MI (zip 48109), about 20 miles SW of Detroit, MI.
1. MonstIR (SteppIR) full-size 40m-6m Yagi-Uda, with 6m reflector kit,
N-connector, and mast plate drilled for 3 inch mast, control box, 200 ft of
