TAA-101/TAA-101S Antenna Actuator Manual | Doc. No. 605169301 Rev. M 1 INTRODUCTION The TAA-101 Antenna Actuator Assembly deploys an omni-directional antenna below the aircraft allowing unrestricted views between the omni and ground sites. Both the TAA-101 and the TAA-101S are designed to avoid line-of-sight obstacles created by aircraft features that might interfere with transmission. This greatly enhances continuous communication between the helicopter and its associated transmit and/or receive site.
TAA-101/TAA-101S Antenna Actuator Manual | Doc. No. 605169301 Rev. M 2 SYSTEM DESCRIPTION The TAA-101 and TAA-101S Antenna Actuator Assemblies consist of the Antenna Actuator that deploys the antenna; a Bracket Mount Assembly used to attach the Actuator to the Helicopter; the Up/Down Box to control the actuator; and the interconnection cables. The main components of the Antenna Actuator are a gear head motor, worm and worm gear assembly.

TAA-101/TAA-101S Antenna Actuator Manual | Doc. No. 605169301 Rev. M The low profile skid-mount bracket assembly (Figure 2) is attached to the helicopter skid by using stainless steel clamps. Since the skid diameters vary on the different makes of helicopters, bracket assemblies are available to accommodate several of the more popular helicopters. Figure 2.
TAA-101/TAA-101S Antenna Actuator Manual | Doc. No. 605169301 Rev. M Deployment of the antenna actuator is controlled by the Up/Down Box which also supplies it with power. There are other deployment control units available as part of an integrated broadcast system (HCP-50, HCP-100, HCP-50-HCII). Please contact BMS for more information on integrated systems. 2.

TAA-101/TAA-101S Antenna Actuator Manual | Doc. No. 605169301 Rev. M 3 INSTALLATION/SETUP NOTE: Installation should only be performed by an FAA Certified A/P or Avionics Technician. Each component should be installed in compliance with FAA regulations and accepted industry practices. Some antenna mounts have been granted STC authorization by the FAA for particular aircraft; other installations may require additional inspection/authorization.
TAA-101/TAA-101S Antenna Actuator Manual | Doc. No. 605169301 Rev. M 6. Install actuator. 3.1 Deciding the Component Locations The placement of the mounting bracket and actuator are a function of aircraft structure, center of gravity, pilot visibility and functionality. The attachment of the mounting bracket must be structurally sound. The location should be such that the pilot can easily see whether the antenna is deployed or not.
TAA-101/TAA-101S Antenna Actuator Manual | Doc. No. 605169301 Rev. M • P/N 810140250 – 2.50” dia. • P/N 810140260 – 2.60” dia. 1. Orient the mount so the antenna will deploy straight down (the notches are facing up). 2. Attach the top clamp to the strut. 3. Loosen the bottom clamp support and adjust the angle so that the bottom clamp mates up with the strut. Figure 19. Cross-tube mount assembly 4. Secure the bottom clamp to the strut. 5. Secure the upper clamp support. 3.3 Cable Routing 1.
TAA-101/TAA-101S Antenna Actuator Manual | Doc. No. 605169301 Rev. M 3.5 Cable Termination Once final cable lengths have been determined after running the cables between the installed components, they may be terminated. 3.6 Antenna Installation To install the antenna onto the TAA-101 Actuator, the actuator will need to be extended first to allow proper access to all the mounting holes. The TAA-101S does not need to extend the actuator prior to antenna installation. 3.6.
TAA-101/TAA-101S Antenna Actuator Manual | Doc. No. 605169301 Rev. M Figure 20. Actuator Installation and Removal tools 1. Ensure the skid mount bracket is mounted to the skid, if not already done. See section 3.2. 2. Retract the actuator so that the omni antenna is in the stow position (if it is not already). 3. If not already positioned, rotate the detent pins (Figure 21) so their beveled ends face up. THIS IS VERY IMPORTANT! FAILURE TO ALIGN THE PINS IN THIS WAY MAY DAMAGE THE PRODUCT! Figure 21.

Aligning the actuator (sealed actuator shown) 5. Insert the square end of the TAA-101 installation tool (P/N 800169391) on the first actuator mounting pin, as shown in Figure 23. Note that the tool is positioned between each washer. Mounting bracket’s spring-loaded Figure 23.
TAA-101/TAA-101S Antenna Actuator Manual | Doc. No. 605169301 Rev. M 6. Slide the tool’s red plunger up, then down quickly and with enough force to push the actuator mounting pin into position. It takes considerable force to ensure the pin slides past the mounting bracket’s spring-loaded detent pin. 7. Repeat step 5 for the other pin. The correctly mounted actuator is shown in Figure 24. Detent pins extend fully across actuator mounting pins Figure 24. Actuator correctly mounted 8.

Using the actuator removal tool on forward and rear pins 2. With the tool positioned correctly, pull the tool back slowly and firmly to lift the actuator mounting pin past the mounting bracket’s spring-loaded catch. 3. Repeat step 2 for the other mounting pin. Broadcast Microwave Services, Inc.
TAA-101/TAA-101S Antenna Actuator Manual | Doc. No. 605169301 Rev. M 4 USER INTERFACE There are several Deployment Control Units available for the TAA-101 and TAA-101S. The Up/Down Box is the only unit with the sole function to deploy and retract the antenna actuator. Other Deployment Control Units have additional features not covered by this documentation. Please refer to the proper documentation for the specific Deployment Control Unit for information on installation, operation and maintenance.
TAA-101/TAA-101S Antenna Actuator Manual | Doc. No. 605169301 Rev. M 5 OPERATION CAUTION: • Follow all procedures precisely to ensure initialization and operation. • The TAA-101 and TAA-101S deployment is for IN-FLIGHT operation ONLY. • The Antenna needs to be properly STOWED (retracted) prior to take-off and Landing. Deploy the antenna by pulling the Actuator Control Switch out and putting it in DOWN position. It takes the antenna about 15 seconds to deploy.
TAA-101/TAA-101S Antenna Actuator Manual | Doc. No. 605169301 Rev. M 6 PREVENTIVE MAINTENANCE In order to ensure system longevity it is highly recommended that the following preventive maintenance procedures be done at the appropriate time. 6.
TAA-101/TAA-101S Antenna Actuator Manual | Doc. No. 605169301 Rev. M 5. Lubricate the mechanism by placing 1/8 in. square of lubricant (101 Moly Grease or equivalent) on each tooth of the brass gear. 6. Retract and deploy the antenna 3 times to work in lubricant. 7. Retract the antenna. 8. Install the actuator onto the mounting bracket using the actuator installation tool, P/N 800169391. See section 3.7 for instructions. Broadcast Microwave Services, Inc.
