34. A Loose Wire?419 viewsThe loose wire is actually a ground wire. The rolling portion fo the fense is grounded via this lead.Jan 29, 2006
armacost035.jpg
33. Personals Ad: "Concrete Pad Sks Standby Pwr Gen!"315 viewsAs noted above, the standby power generator isn't (yet) installed here. Who knows...maybe it'll never be installed, but if it is, this is where it'll go.Jan 29, 2006
armacost034.jpg
32. Looking down on the Activated Site381 viewsHere's the bird's-eye view looking down at the BTS equipment mounted on the far pad.Jan 29, 2006
armacost033.jpg
31. Cable Termination to BTS Jumpers349 viewsHere's a nice photo of the the cable terminations for the hardline cable to/from the roof, and the jumper to the equipment cabinet. The colored bands identify what cable is connected to what antenna.Jan 29, 2006
armacost032.jpg
30. BTS Installed and Humming314 viewsThe site is active. This photo is looking down on the site BTS equipment cabinet through the roof fence. You'll see more of the fense in a later photo.Jan 29, 2006
armacost030.jpg
29. Which Way Tray?358 viewsIt's now January, 2006. The site is active (but without a backup power generator). It seems that the installers missed putting all of the covers on the cable tray. Too bad.Jan 29, 2006
armacost029.jpg
28. Close up of the Site Name Sign527 viewsIt's for sure...We'll call this Armacost!Jan 29, 2006
armacost028.jpg
27. The Name Goes On Before the Quality Goes In323 viewsThe pad has been poured, again, and the fense is on it's tracks. No BTS yet, but the site sign has gone up announcing to the world that this is Verizon's Armacost site!Jan 29, 2006
armacost027.jpg
26. Anyone for a Tumble?265 viewsThe concrete mixer has done its job and is ready to go home, again!Jan 29, 2006
armacost026.jpg
25. It's Raining, It's Pouring (Concrete)274 viewsHere's the new re-poured pad. It's just been poured. There'll be a cure period to let it harden before moving the equipment into the area.Jan 29, 2006
armacost025.jpg
24. It's Concrete Pour Day...Again270 viewsThe wood frames are in place and braced for the pour...again. Notice the very nice cable terminations at the far end of the cable tray. You'll see these again, later.Jan 29, 2006
armacost024.jpg
23. An outside view fo the BTS Equipment Area260 views...with the sliding fense not installed on the track, yet.Jan 29, 2006
armacost023.jpg
22. Another View of the New Generator Wood Frame261 viewsYup, it's clearly rotated 90 degrees from before. Oh well.Jan 29, 2006
armacost022.jpg
21. Huh? What Happended to the Concrete Pad?299 viewsIn a surprising twist, the concrete pad has been hammered out and new frames and conduits installed. What gives? According to the work crews, it seems that the generator pad was installed 90 degrees off. Go back in the gallery and look and you'll see what I'm talking about. Because of the little error, weeks were apparently lost in site activation...not to mention $$$ (which I didn't, okay?).Jan 29, 2006
armacost020.jpg
20. The Scaffolding is Down305 viewsHere's a good shot of the clock tower with the scaffolding removed. Nice pic at sunset, eh?Jan 29, 2006
armacost019.jpg
19. Now You See the Cables...Now You Don't265 viewsAnd the cables in the BTS area are also safely tucked away under the cover of the tray.Jan 29, 2006
armacost018.jpg
18. Now You See the Cables...Now You Don't284 viewsThe cables are now safely tucked away under the cover of the tray, now installed.Jan 29, 2006
armacost017.jpg
17. Clock Tower Painting Underway279 viewsA rear view of the re-painted clock tower.Jan 29, 2006
armacost016.jpg
16. Clock Tower Painting Underway298 viewsYet another view of the re-painted clock tower.Jan 29, 2006
armacost015.jpg
15. Clock Tower Painting Underway273 viewsThe panels are fully installed and are being painted and textured to match the building.Jan 29, 2006
armacost014.jpg
14. Installing the Telco Interface and Power Switching Cabinets383 viewsThe large cabinet on the right (with the open door) is to house the telco interface. A telco dataline is used to connect this cell site back to Verizon's mobile telephone switching office. The two smaller cabinets on the left, starting at the far left, are the power breaker panel, and the power generator transfer switch. The transfer switch senses loss of commercial power and automatically starts the generator (yet to be installed) and transfers power to the generator once stabilized. The reverse occurs when the commercial power is restored for a minimum period of time.Jan 29, 2006

13. Securing the Cables and Painting272 viewsThings are moving forward downstairs, too! Jan 29, 2006
armacost012.jpg
12. Close-up of GPS antenna and top of Cable Tray323 viewsAs noted before, the cables are carefully pulled on to the roof so as to prevent kinks. The GPS antenna provides system synchronization time signals. This location is inferior as it can been seen from the ground. A better location would have been on the roof away from the edge so as to hide this element. Jan 29, 2006
armacost011.jpg
11. Cables are now in the Cable Tray288 viewsWe're getting closer! Notice that the cables make a gentle (less than 90 degree) bend at the bottom of the ladder where it connects to the tray in the hallway. Bending cables too much can kink them. Kinking can cause excessive signal transmission losses. Not a good thing! Also notice that the GPS antenna is now installed--quite visibly--at the top of the cable tray on the roof. More in the next photograph...Jan 29, 2006
armacost009.jpg
9. More Cable Tray Installation285 viewsHere's a further view of the cable tray as it transitions from the hallway leading from the side of the building over and down to the BTS equpment housing area.Jan 29, 2006
armacost010.jpg
10. Securing the Coaxial Cables in the Tray288 viewsA tech secures the cables to the tray. Notice that the cable tray extends out a bit from the edge of the wall. This will connect with the vertical portion of the tray heading to the roof.Jan 29, 2006
armacost008.jpg
8. Installation of the Cable Tray to the Roof307 viewsThe techs are installing the cable tray. Once installed, the coaxial cables will be lashed to the ladder arms to provide for support, and to prevent excessive bending of the coaxial cables.Jan 29, 2006
armacost007.jpg
7. A Close-Up View of Two Sectors of RF-Transparent Panels261 viewsThis is a close-up of the rear of the bell tower modified to enclose the antennas. Jan 29, 2006
armacost006.jpg
6. A Close-Up View of Two Sectors of RF-Transparent Panels297 viewsYet another view of the bell tower being modified to enclose the antennas. Jan 29, 2006
armacost005.jpg
5. A Close-Up View of Two Sectors of RF-Transparent Panels270 viewsHere's a close-up of the bell tower being modified to enclose the antennas. The cut-outs on the front and left side of the tower are the RF transparent panels. Jan 29, 2006
armacost004.jpg
4. BTS Pad and Cable Termination308 viewsThe raised concrete pad is to support the BTS equipment. The cables that dead-end in the wall-mounted tray will connect the roof antennas to the BTS.Jan 29, 2006
armacost003.jpg
3. Base Telecommunications Station Equipment337 viewsThis new addition to the existing structure at the rear of the building is to house the BTS equipment, plus a future standby power generator, power switching equipment, and a telephone interface panel. The standby power generator pad is the the one nearest the fence. The BTS equpipment pad is to the rear-left in this photo. Later, things will change a bit...oops!Jan 29, 2006
armacost001.jpg
1. Antennas to be Hidden in Clock Tower388 viewsThree of four sides of the exsting clock tower had walls partially removed to permit the installation of RF-transparent fiberglass panels. As you'll see later, once the antennas are installed behind the panels, the panels are painted and textured to match the rest of the structure, thus hiding the antenna locations.Jan 29, 2006
armacost002.jpg
2. Routing the Antenna Cables up to the Roof396 viewsThe coaxial cables for the antennas, including the GPS antenna, are loosely placed against teh wall going up to the roof. As you'll see later, these cables will be secured in a cable tray. At this time the GPS antenna is not yet installed.Jan 29, 2006
