Two Sectors - One into a hillside!411 viewsAs seen in the accompanying photo, the left-pointing antennas (sector) seem to provide excellent coverage for the hillside, and not much beyond it. It would be interesting to know how much power this site and antennas produce, and whether any portion of the hillside is in an RF controlled zone. The hillside, as you can see in the photo, is quite accessible to the general public.

Two Sectors - One into a hillside!380 viewsThis sprint site isn't for roadway coverage. One sector (the one facing right in this photo) faces a group of homes. The sector facing left in the photo points DIRECTLY INTO A HILLSIDE! Very strange! See the accompanying photo for more details about the aiming of the left-hand sector.

Sprint - Microcell using Sanders CATV radio423 viewsSprint (especially in conjunction with Cox) deployed a significant number of the Sanders cable TV/cell interface. This site uses very low gain antennas (the two outside antennas are for reception from the users, and the center antenna is for transmission to the users). Sprint has built its own CATV-like wireless system to connect many of its sites back to its MTSOs.

The lower carrier does not use diversity reception (two receive antennas spaced so as to better receive lower power mobile handsets). The upper carrier does use diversity. Usually, in diversity configurations, the two receive antennas are on the outsides of the sector, and the transmit antenna is located inside, adjacent to one of the receive antennas.
