About this file
This is a tower inspection report and antenna installation documentation for a WLPB TV 990-foot tower inspection conducted on August 18, 2025, related to a transmission line installation project for Louisiana's LETA (Louisiana Educational Television Authority). The file contains detailed section-by-section inspection findings documenting structural deficiencies, maintenance issues, and equipment problems throughout the tower, including loose and improperly routed flexible transmission lines, missing hangers across multiple sections (sections 5, 6, 10, 11, 12, 13, 18), bent and damaged horizontal members (section 15), damaged diagonal members (section 39), improperly secured Kellum grips, rust on safety climb cable systems, and a missing safety climb system on the transition climbing ladder from bay 1 through bay 4. The documentation also includes photographs illustrating typical views of identified deficiencies and mechanical specifications for a cascade antenna assembly (project 40177) manufactured by Electronics Research Inc., detailing lifting procedures, shipping details, mounting specifications, and connection requirements for a 4,400-pound antenna system designed for installation on the tower top plate.
The inspection report provides detailed photographic evidence and technical specifications necessary for remediation planning and antenna installation coordination. The antenna installation documentation includes comprehensive lifting and shipping details with specific rigging attachment points, mounting flange specifications, torque requirements for hardware assembly, and plumbing tolerances requiring the antenna to be within 0.1 degrees from vertical. Bill of materials and mechanical parameter drawings specify hardware grades (ASTM A325 bolts, ANCO locknuts, F436 flat washers), cable specifications, grounding kits, lightning protection components, and climbing pole assemblies. The contract appears to address tower maintenance, repair of identified structural and transmission line deficiencies, and installation of updated antenna equipment to restore the transmission facility to proper operational standards.

10. BEND TONGUE OF CABLE GRIP SUPPORT (ITEM #14) TO CAPTIVATE THE CABLE GRIP.
11. APPLY TEFLON TAPE TO THREADS ON TOP OF CLIMBING POLE.
CONNECTION NOTES:
1. FOR PROPER PERFORMANCE AFTER INSTALLATION, PLUMB THE ANTENNA TO WITHIN 0.1°
FROM VERTICAL (5/8 INCH IN 30 FEET). A KIT OF SHIMS IS INCLUDED WITH THE ANTENNA.
AS REQUIRED FOR PROPER PLUMB, GAPS BETWEEN ANTENNA MOUNTING FLANGE AND TOWER
TOP PLATE MUST BE FILLED USING THE SUPPLIED SHIM KIT OR SUITABLE STEEL SHIM STOCK.
2. ANTENNA MOUNTING FLANGE BOLTED CONNECTION SHALL BE BROUGHT TO A SNUG-TIGHT CONDITION
WHERE JOINT TIGHTNESS IS ATTAINED WITH A FEW IMPACTS OF AN IMPACT WRENCH OR FULL EFFORT OF AN IRONWORKER USING AN ORDINARY SPUD WRENCH TO BRING THE PLIES INTO "FIRM" CONTACT, AND THEN AN ADDITIONAL 1/3 TURN (120° ± 30°) APPLIED TO THE NUT OR BOLT HEAD FOR FINAL BOLT TIGHTENING. A SYSTEMATIC APPROACH SHALL BE USED WHEN TIGHTENING THE BOLTS STARTING WITH THE MOST RIGID PART OF THE JOINT. THE PART NOT TURNED BY THE WRENCH SHALL BE
PREVENTED FROM ROTATING DURING THIS OPERATION.
3. IT IS ERI'S INTENTION THAT AN ANCO LOCKNUT BE PROVIDED FOR ALL HIGH-STRENGTH ASTM A325 BOLTED CONNECTIONS, UNLESS OTHERWISE NOTED. FLAT WASHERS ARE REQUIRED ON MOUNTING FLANGE CONNECTIONS.
