DRAWINGS for Ant. Maint. and Support Services.pdf

This document is a technical drawing set for antenna maintenance and facilities support services at the Philippines Transmitting Station Tinang Transmitter Plant. The attachment consists of four sheets showing detailed site layouts, antenna configurations, and facility infrastructure.

Sheet 1 presents a keyplan of the entire facility identifying four compound locations: Transmitter/Powerplant Compound (marked 1), Substation Compound (marked 2), Subtraction Compound (marked 3), and PNP Compound (marked 4). The drawing indicates Switch Bay locations (SB-1, SB-3, SB-4) and references to detailed antenna and transmission line drawings. Sheet 2 provides detailed views of antenna dish locations at the transmitter compound, rhombic antennas at Switchbay-3, and the SIS antenna dish system, along with facility photographs showing antenna installations and transmission infrastructure. Sheet 3 displays tower antenna plans, dissipation/transmission line schematics, and tower antenna isometric layouts with structural steel support frames and transmission/dissipation lines, including multiple photographic documentation of antenna tower installations. Sheet 4 presents a detailed schematic of Switch Bay-1 at 1:100 scale with photographic evidence of the switch bay facilities, transmission line connections, and structural conditions. The drawings are scaled and include both technical diagrams and field photographs documenting existing facility conditions for maintenance and support service planning purposes.
