With 8741 ft., Mount Irish is the tallest peak in the Pahranagat Range, overlooking most of Tikaboo Valley and the northern Nellis Ranges. This makes it a prime location for a radio repeater facility. And sure enough, there appears to be quite a selection of radio antennas and microwave dishes along with some buildings and trailers on the plateau on top. As you can see in the photos below, the slopes are very steep, and there is no road access to the top. Just like Bald Mountain, the fully automated and unmanned facility is serviced by helicopter.

Based on various observations we suspect that the Mt. Irish facility was a central hub in the old ACMI Range system used for the Red Flag exercises. The old ACMI sites on Flat Top and on Badger Mountain were pointed to Mount Irish. The hub for the new system appears to be in a different location, and it seems that the Mount Irish facility now is one of the 15 transceiver stations that are located all around the ranges. It is also used as a relay for the Lincoln County Sheriffs office, and by Lincoln County Telephone for the microwave link that provides phone service in Rachel. Contrary to a common misconception there is no evidence for a connection between this site and the Bald Mountain site.

This photo of the Mt. Irish radio facility was taken on 11/30/2003 from Hwy. 375, about 13.5 miles south of the peak. The top is only accessible by helicopter. The landing pad is on the right.

This close-up of the Mount Irish radio facility shows the large antenna tower, several support buildings and storage containers and at least two solar panel arrays.
Looks like a lightning protector and some non-directional antennas at the top of the tower. They are probably used as a relay for the Lincoln County Sheriffs radio system.
The two smaller dishes below the top are probably part of the new ACMI Range system, which allows real-time 3D tracking of planes during the Red Flag exercises.
The large dish at the bottom points roughly towards Rachel. It is used by the Lincoln County phone company to provide telephone and Internet access for Rachel. There are no land lines to Rachel, but all calls go through this dish and its counterpart above the Lincoln Mine on the north side of Tempiute Mountain. Photo taken on 7/01/2002 from a location about 4 miles southwest of the peak.

The antenna tower on the left and the radar reflector on the right are also located on Mount Irish, on a slightly lower plateau north of the top. Photos taken on 7/01/2002 from a location east of Mt. Irish.
