17 - Side view of Our Little Friend1201 viewsJanuary 2, 2005 was a cold, damp day in Southern California, but I managed to snap a photo of our little tree to better show the new antennas mounted off of the trunk, and the new sickly green quad antennas. Also notice a small "Keep Out" sign at the lower left corner of the front fence. I'm sure that it is very effective.
|
|
08 - Faux Branches Installed1188 viewsOur little tree is taking shape now the branches have been installed. Notice the unprotected coaxial cables running to the tree near the base (right side).
|
|
18 - Our little friend has changed and grown!1162 viewsThis photo, taken in November, 2004 shows (1) that the second-to-the-right antenna has been changed out without much regard to color matching, (2) that a new dual-band antenna has been added on trunk below the prior-existing antennas, and (3) that the faux branches have been extended down the trunk to provide partial cover for the new antenna.
Note that the replacement dual-band antenna has its four cable ports visible on the bottom of the antenna, unlike the existing with hidden rear connectors. Most unsightly!
Sad, sad little tree.

|
|
Not part of an underground water river...551 viewsThe water bottle is not part of the CEV.
|
|
Cabinet Pads in the Transmitter Vault549 viewsThe raised concrete pads lift the transmitter and air conditioning cabinets off of the floor. That's real handy where water might pool around it, don't ya know! Photo by Bill Cloutier.
|
|
KMLT Almost Buried - Just a few weeks of work left!544 viewsThe underground transmitter building is almost complete. Just waiting on the stairs and hatch to be installed. The fencing is still not in final shape at the antenna. Most of the construction 'stuff' has left the site for points unknown. April 2005.
|
|
KMLT Almost Buried542 viewsIf you compare this photo with past photos you'll notice that half the transmitter building is now buried. When complete only the ground level access in the foreground of the building will remain. The pullbox to the left of center is for electrical power. The pullbox to the far right is for the coaxial egress point to feed the antenna.

|
|
1. Antennas to be Hidden in Clock Tower496 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.
|
|
14. Installing the Telco Interface and Power Switching Cabinets496 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.
|
|
KMLT's Antenna Fence Under Construction494 viewsThe fence being constructed is to keep the hikers in the area away from the antenna site. At the time this photo was snapped KMLT was operating from its old (aux) transmitter site some miles away.
|

|
|
29. Which Way Tray?474 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.
|
|
Where's the Transmitter?473 viewsLooking down from near the antenna, the underground FM transmitter housing is nowhere to be seen! May 2006.
|
|
Cable route in/out of the CEV473 viewsThis trench will house the power and telephone cable conduits into and out of the CEV, as well as the coaxial cables to the base of the light standard.

27. The Name Goes On Before the Quality Goes In443 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!
|
|
12. Close-up of GPS antenna and top of Cable Tray439 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.

|
|
21. Huh? What Happended to the Concrete Pad?412 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?).

11. Cables are now in the Cable Tray407 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...
|
|
9. More Cable Tray Installation404 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.
