In the database, 170.050 NPS Dome. Could someone expound on what 'NPS Dome' is?

To the best of my knowledge, "NPS Dome" refers to the National Park Service's repeater on the "Dome" mountain near Bandelier National Monument. That site provides pretty good coverage in very mountainous terrain.
This is incorrect.See posts #11 & 12 of

Submitted to DB. Operations, mainly occur on this channel in p25. (Caves/visitor center area) 164.60000 NAC 4CE A repeater system is used in the caves which one will notice sign upon entering the natural entrance of radio wave radiation. Similar to a subway repeater system. On the top the...forums.radioreference.com
That road to Dome!! Nice website btw.Hello,
Dome NPS is a lookout/repeater site located on St. Peter's Dome. Here is a document that is on my website that is addressed in my signature line. It will give you a good history of the Dome Lookout as well as many others in the Santa Fe National Forest.

The Dome Fire of 1996 cleared out all the timber in the entire region making the lookout very easy to spot. Do to fires around Los Alamos National Lab, the lookout is maintained as a repeater site, but not as a lookout. Cerro Pelado is the lookout that is used for visual spots.
Many agencies use the Dome repeater site. Bandelier National Monument, Cibola National Forest, and Santa Fe National Forest. My website below lists those frequencies.
Here are two pictures from 2006. Been a long time since I have hiked up there.

Cibola National Forest also has a repeater on Dome Mountain

If the elements are vertical, think vertical polarization. The same applies if the elements are horizontal, think horizontal polarization.I'm not an expert on radio either, but know a little bit due to the men in my life (dad and late husband) who were both hams. I got my license when I was in my college years. The directional antennas are called "beam antennas." They might be for links, although their element lengths of the antennas on the right (right picture) seem to suggest VHF. The shorter element antennas on the left look like UHF antennas, but their elements seem real short. I can't remember if the elements are placed vertically that means the signal is horizontally polarized and horizontal antennas mean a vertically polarized signal. I got the two mixed up all my life. The link antennas (UHF federal band) antennas I saw while with dad and my husband had elements in a vertical position or maybe I'm forgetting those as well. Another possible explanation is that Dome is a remote base for some system, maybe the NPS or the Santa Fe NF, but I know little of the topography of the area. A remote base is in a location where it can "see" or TX/RX all the repeaters in the system.
Somebody who is better at this than both of us combined may be able to enlighten us. I never went beyond the technician class license, but hey, when I got my it Morse code was still required. Not that it helps me figure out those antennas in this case.

Just a reminder / caution: USFS has a habit of publishing the P25 NAC as decimal vs. hex, as shown in this table. Therefore, the dual-mode repeaters at Cerro Pelado and Abrigo have hex NACs of:

Just a note to remember when programming.
Also note that "100" and "123" should really read "100.0" and "123.0" for the CTCSS tones. These 2019 spreadsheets were rushed, apparently with poor formatting and have, as well, dropped the still-existing repeater transmit tones, which are, I believe, still the same as in the 2016 spreadsheets.
