UTARC 2003 Aerospace Engineering Satellite Dish

In winter, 2003, a research group in the Aerospace Engineering department began to install a new three meter dish for satellite communications and tracking experiments on top of the east penthouse of WRW. Our new neighbors were nice enough to facilitate the pouring of a new concrete base for a second, bracketed tower for UTARC next to the east penthouse as part of the project!

It was a grey, cloudy day when these photos were taken. The conduit running up the side of the penthouse is new, as is the railing on the near side of the penthouse - before, the railing on top of the penthouse was open to the west.
New conduit penetrating the roof to the floor below. The larger conduit might be used for feed line.
A new tower pad for N5XU. This pad is twice as thick as the one our current tower sits upon.
Another view of the tower pad.
Looking down at the tower pad from the staircase. The new tower will be bracketed to the penthouse at this point.
A large NEMA box that terminates the conduit from inside the building.
The new three meter dish.
A small Glen Martin Engineering antenna roof mount. It is bolted to the concrete roof, but does not yet have anything attached to it.
A closeup of how the antenna support structure is attached to the roof of the penthouse.
The rotation mechanism of the big three meter dish.

Another view of the dish rotation mechanism. Notice that the dish does not yet have a feed.
The new view facing west and looking at the UTARC shack.
The new view to Darryl K. Royal Texas Memorial Stadium.

Looking from the east penthouse to the new satellite dish on the west penthouse.
The satelite station at N5XU uses cross-polarized yagis on 144 MHz and 435 MHz, and a "barbecue grill" style dish for 2.3 GHz. The black cross-boom is fiberglass and non-conductive.
